Efficient Synthesis of Pyrido[3,2-c]coumarins via Silver Nitrate Catalyzed Cycloisomerization and Application to the First Synthesis of Polyneomarline C

Herein, we report an efficient method for the synthesis of the pyrido[3,2-c]coumarin scaffold, one of the privileged heterocycle-fused coumarin scaffolds, via a AgNO3-catalyzed cycloisomerization of 4-(propynylamino)coumarins obtained from diverse 4-hydroxycoumarins.

Ultrahigh-performance blue organic light-emitting diodes based on SiO2 coated Ag nanocubes and its working mechanism

Ag nanocubes coated with SiO2 shell were synthesized and incorporated into the emission layer of blue organic light-emitting diodes to improve the device performance. The thickness of SiO2 shell was changed to adjust the distance between Ag NCs and excitons to investigate the coupling of the localized surface plasmon resonance (LSPR) of Ag NCs and the radiation of excitons. In addition, the host materials with different carrier transporting properties are used to study the correlation between the LSPR enhanced exciton radiation and the exciton recombination zone in emission layer. Research findings demonstrate the thickness of SiO2 shell and the exciton recombination zone together affect the coupling of LSPR and exciton radiation. Using the Ag NCs coated with 15 nm SiO2 shell and the bipolar host material of 2,6-bis(3-(carbazol-9-yl)phenyl)pyridine (26DCzPPy), the blue OLED achieved an very high improvement in the current efficiency. The maximum peak current efficiency of the blue OLED with Ag NCs reached to 97 cd/A, being nearly 4 times of that of the device without Ag NCs.

Cooperative phenomenon of vapochromism and proton conduction of luminescent Pt(ii) complexes for the visualisation of proton conductivity

The luminescent and proton conductive Pt(ii) complex [PtCl(tpy-o-py)]Cl and its HCl adduct [PtCl(tpy-o-pyH)]Cl-2 (o-Pt and o-Pt center dot HCl, respectively; tpy-o-py = 2,2 ‘:6 ‘,2 ”-terpyridine-6 ‘,2 ”’-pyridine) were synthesised and their crystal structures, vapochromic behaviour, and proton conduction, were investigated and compared to those of the para isomers [PtCl(tpy-p-py)]Cl and [PtCl(tpy-p-pyH)]Cl-2 (p-Pt and p-Pt center dot HCl, respectively; tpy-p-py = 2,2 ‘:6 ‘,2 ”-terpyridine-4 ‘,4 ”’-pyridine). X-ray structure analysis revealed that the intermolecular metallophilic (PtMIDLINE HORIZONTAL ELLIPSISPt) interaction was negligible in o-Pt but effective in o-Pt center dot HCl. Reversible transformation between o-Pt and o-Pt center dot HCl coupled with significant colour and luminescence changes was achieved by four different external stimuli, namely: exposure of o-Pt to humid HCl gas to form o-Pt center dot HCl, heating, exposure to MeOH vapour, and finally drying in air to regenerate the original o-Pt. The intraligand pi-pi* orange emission observed for o-Pt exhibited negligible dependence on the relative humidity (RH). Conversely, o-Pt center dot HCl exhibited red metal-metal-to-ligand charge-transfer (MMLCT) phosphorescence at 725 nm, originating from effective intermolecular Pt-Pt interactions, and interesting vapochromic behaviour that was dependent on the RH. Notably, o-Pt center dot HCl presented higher conductivity than the p-Pt center dot HCl isomer at RH < 80%. This trend was reversed at RH values > 80%, probably owing to the second water-adsorption-induced transformation of p-Pt center dot HCl. The cooperative phenomenon between the proton conduction and vapochromic behaviour observed for both o-Pt center dot HCl and p-Pt center dot HCl should allow the visualisation of the proton-conducting pathway, without the need for a bulk electrode, via the absorption and emission colours at both macroscopic and microscopic levels.

The synthesis, biological evaluation and fluorescence study of chromeno[4,3-b]pyridin/quinolin-one derivatives, the backbone of natural product polyneomarline C scaffolds: a brief review

Coumarins (natural, as well as synthetic) are an important class of heterocycles having immense potential for industrial and medicinal applications. Coumarin-fused heterocycles, mainly pyridine or quinoline, possess a plethora of biological attributes such as anti-bacterial, anti-fungal, and anti-cancer properties, in addition to being fluorescence active. This review aims to assess the past and current status of research works associated with these compounds in light of the vast body of work on different synthetic methodologies, bioactivity and fluorescence studies by looking specifically at chromeno[4,3-b]pyridin/quinolin-one derivatives, the backbone of natural product polyneomarline C scaffolds, during the past two to three decades. The synthesis of chromeno[4,3-b]pyridin/quinolin-one derivatives by the construction of either pyridine, or quinoline, or coumarin rings via classical reaction protocols, ultrasound-mediated reactions, microwave-mediated reactions, organo-catalyzed reactions, transition metal-catalyzed reactions, metal-free ionic liquid-mediated reactions and green reaction protocols starting from suitable precursors has been reported in the literature. This review also aims to be a prospective resource for the uninitiated work towards the development of new synthetic strategies, exploring the newer domains of biological and the fluorescence activity studies of chromeno[4,3-b]pyridin/quinolin-one derivatives.

Mechanistic Origins of Regioselectivity in Cobalt-Catalyzed C(sp(2))-H Borylation of Benzoate Esters and Arylboronate Esters

Synthetic and mechanistic investigations into the C(sp(2))-H borylation of various electronically diverse arenes catalyzed by bis(phosphine)pyridine ( IPr PNP) cobalt complexes are reported. Borylation of various benzoate esters and arylboronate esters gave remarkably high selectivities for the position para to the functional group; in both cases, this regioselectivity was found to override the orthoto-fluorine regioselectivity, previously reported for ((PNP)-P-iPr)Co borylation catalysts, which arises from thermodynamic control of C(sp(2))-H oxidative addition. Mechanistic studies support pathways that result in para-to-ester and para-to-boronate ester selectivity by kinetic control of B-H and C(sp(2)-H) oxidative addition, respectively. Borylation of a particularly electron-deficient fluorinated arylboronate ester resulted in acceleration of C(sp(2))-H oxidative addition and concomitant inversion of regioselectivity, demonstrating that subtle changes in the relative rates of individual steps of the catalytic cycle can enable unique and switchable site selectivities.

Synthesis and Reactivity of Heptamethylcyclohexadienyl Rhodium(III) Complexes

We report the synthesis and reactivity of the half-sandwich rhodium(III) complexes with the fully methylated cyclohexadienyl ligand C6Me7, which is analogous to the classical Cp*. The starting complex [(C6Me7)RhCl2](2) (4) was obtained in high yield (92%) by the reaction of [(cyclooctene)(2)RhCl](2) with the readily available 6-methylenehexamethylcyclohexadiene-1,4 (C6Me6=CH2) followed by addition of HCI. Reactions of complex 4 with common two-electron ligands L gave the expected adducts (C6Me7)RhCl2L (L = pyridine, P(OEt)(3), PPh3) in high yields (80-90%). At the same time, the interaction of 4 with the stronger ligand (BuNC)-Bu-t led to the replacement of the C6Me7 ligand. The cationic complex [(C6Me7)Rh(dppe)Cl]PF6 and the dicationic complex [(C6Me7)Rh(C6Me6)](BF4)(2) were obtained by abstraction of chlorides from 4 with TlPF6 or AgBF4 in the presence of the corresponding ligands. The reaction of 4 with 2-phenylpyridine in the presence of CsOAc proceeded via CH activation and gave the cyclometalated product (C6Me7)Rh(C6H4-Py)Cl in 85% yield. Accordingly, the catalytic reaction of 2-phenylpyridine with 3-hexyne in the presence of 4 (5 mol %) gave the 9,10-diethyl-8a-azaphenanthrene cation in 61% yield. However, the catalytic efficientcy of 4 was lower than that of the classical catalyst [Cp*RhCl2](2), possibly because the displacement of the cyclohexadienyl ligand interrupted the catalytic cycle. The DFT calculations suggested that the electron-donating ability of cyclic pi ligands in the rhodium complexes (CnRn)RhCl2CO decreases in the order CnRn, = C5Me5 > C6Me7 > C5H4OMe approximate to C5Me4CF3 > C5Me3(COOMe)(2) approximate to C5H4Me > C5H5 > C5H4F approximate to C5H4COOMe > C(5)a(4)CF(3).

Optimal functionalization of a molecular electrocatalyst for hydride transfer

Optimization of hydride transfer (HT) catalysts to enhance rates and selectivities of (photo)electroreduction reactions could be a crucial component of a sustainable chemical industry. Here, we analyze how ring functionalization of the adsorbed transient intermediate 2-pyridinide (2-PyH-*)-predicted to form in situ from pyridine (Py) in acidified water at a cathode surface and to be the key to selective CO2 photoelectroreduction on p-GaP-may enhance catalytic activity. Earlier studies revealed that 2-PyH-*’s instability results from a protonation side reaction producing adsorbed dihydropyridine (DHP*), which is relatively HT-inactive. Reducing the electron density on 2-PyH-* could limit this protonation, with the trade-off that it may become less active for HT from 2-PyH-*- R to CO2. We explore here how Py functionalization affects the electron distribution and in turn tunes the catalytic performance of 2-PyH-*. We indeed find that electron-withdrawing groups could enhance the stability of 2-PyH-* by reducing its electron density on the ring. Furthermore, we find that the change in the number of electrons on the substituting group of the hydride donor is a good descriptor for both the stability against protonation and the magnitude of the HT barrier. We predict that -CH2-CH2F is the best candidate substituent, as it significantly improves the stability of 2-PyH-* with only a small increase in HT barrier. -CH=CH2 and -CH2F also could be promising, although they require further investigation due to a larger HT-barrier increase.
