Noble-metal photosensitizers and water reduction co-catalysts (WRCs) still present the highest activity in homogeneous photocatalytic hydrogen production. The search for earth-abundant alternatives is usually limited by the time required to screen new catalyst combinations; however, here, we utilize newly designed and developed high-throughput photoreactors for the parallel synthesis of novel WRCs and colorimetric screening of hydrogen evolution. This unique approach allowed rapid optimization of photocatalytic water reduction using the organic photosensitizer Eosin Y and the archetypal cobaloxime WRC [Co(GL1)(2)pyCl], where GL1 is dimethylglyoxime and py is pyridine. Subsequent combinatorial synthesis generated 646 unique cobalt complexes of the type [Co(LL)(2)pyCl], where LL is a bidentate ligand, that identified promising new WRC candidates for hydrogen production. Density functional theory (DFT) calculations performed on such cobaloxime derivative complexes demonstrated that reactivity depends on hydride affinity. Alkyl-substituted glyoximes were necessary for hydrogen production and showed increased activity when paired with ligands containing strong hydrogen-bond donors.

Three hydroxymethyl bridged Cu(ii) complexes of a pyridoxal Schiff base ligand 4-((E)-(2-(pyridin-2-yl)ethylimino)methyl)-5-(hydroxymethyl)-2-methylpyridin-3-ol (LH) have been synthesized and characterized on the basis of spectroscopic, elctrochemical and structural properties. The X-ray crystal structures of the complexes reveal dual denticity of the ligand, bidenticity in the absence of a co-ligand as in complex1, and tridenticity in the presence of a co-ligand such as SCN-/N(CN)(2)(-)as in complexes2and3. The complexes, though binuclear in the solid state, exist as a monomeric unit in solution due to the exceptionally long axial Cu-O-hydroxymethyl(2.4-2.5 angstrom) bond. All three complexes show efficient catalytic activities towards the aerial oxidation of 3,5-ditertiarybutylcatechol (DTBCH2) withk(cat)values of 5.38 x 10(4)h(-1), 1.18 x 10(5)h(-1)and 1.06 x 10(5)h(-1)in methanol. Complexes1and2also act as a selective sulphide ion sensor withK(b)values of 6.6 x 10(3)M(-1)and 8.1 x 10(3)M(-1), respectively, while their respective L.O.D. values are 3.4 mu M and 3.2 mu M.

A new metal-free procedure allowing Csp(3)-N bond formation through coupling of pyridotriazoles and weakly nucleophilic anilines has been developed. This sustainable reaction shows high tolerance towards functional groups (ketones, free alcohols) leading to 2-picolylamine derivatives. The key to our success is the use of a catalytic amount of TBAB and water as a co-solvent leading to the formation of pyridylalkylamine derivatives. As this coupling tolerates the presence of Csp(2)-Br bond on both partners of the reaction, we performed a sequential one-pot reaction between functionalized triazolopyridines and anilines followed by a second coupling with N-tosylhydrazones leading to the formation of Csp(3)-N and Csp(2)-Csp(2) bonds.

The control of the stereochemistry of macromolecules is a very important goal, and coordination-insertion polymerization is superior with respect to the other polymerization methods for its achievement. In this contribution, we focus on Pd(II) homogeneous catalysts for the stereocontrolled synthesis of CO/vinyl arene polyketones. We developed a library of aldo- and keto-iminopyridine ligands N-N’ that feature an alpha- or beta-naphthyl or anthracenyl moiety on the imino nitrogen atom (N-imm). With such ligands, the Pd(II) monocationic complexes [Pd(CH3)(CH3CN)(N-N’)][PF6] were synthesized. NMR spectroscopy shows that in solution, each complex exists as an equilibrium mixture of cis and trans stereoisomers, the latter having the CH3 ligand opposite to the Pd-N-imm bond. The isomeric population depends on the N-N’ ligand: an almost 1:1 ratio is found for the ketimine complexes, whereas those with the aldimines show a preference for the trans geometry. These complexes generate very efficient catalysts for the CO/vinyl arene copolymerization. Catalyst performances depend both on the nature of N-N’ and of the vinyl arene comonomer. The ketimine-based catalysts are more stable and more productive than the aldimine counterpart, leading to prevailingly syndiotactic macromolecules of high M-w (up to 280 kDa). The aldimine derivatives produce copolymers with isotactic and syndiotactic stereoblocks of different lengths depending on the vinyl arene. The effect of the prochiral monomer on the copolymer tacticity is steric in nature as demonstrated by the stereochemistry of the obtained CO/4-fluorostyrene polyketone, whose synthesis is reported here for the first time. As a conclusion, we have now demonstrated that when catalysts with nonsymmetric ancillary ligands are used, and stereoisomers are present, the stereochemistry of the copolymerization is driven by both the catalyst isomeric distribution and the prochiral comonomer.

Schiff bases (SB) obtained from S-methyl dithiocarbazate and aromatic aldehydes: salicylaldehyde (H2L1), ovanillin (H2L2), pyridoxal (H2L3) and 2,6-diformyl-4-methylphenol (H3L4), and their corresponding Zn(II)complexes (1-4), are synthesized. All compounds are characterized by elemental analyses, infrared, UV-Vis, nuclear magnetic resonance spectroscopy and mass spectrometry. The structures of H2L2 and [Zn-2(L-1)(2)(H2O) (DMF)] (1a) (DMF = dimethylformamide) are solved by single crystal X-ray diffraction. The SB coordinates the metal center through the Ophenolate, Nimine and Sthiolate atoms. The radical scavenging activity is tested using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, with all ligand precursors showing IC50 values similar to 40 mu M. Cytotoxicity studies with several tumor cell lines (PC-3, MCF-7 and Caco-2) as well as a non-tumoral cell line (NHDF) are reported. Interestingly, 1 has relevant and selective antiproliferative effect against Caco-2 cells (IC50 = 9.1 mu M). Their antimicrobial activity is evaluated in five bacterial strains (Klebsiella pneumoniae, Acinetobacter baumannii, Listeria monocytogenes, Pseudomonas aeruginosa and Staphylococcus aureus) and two yeast strains (Candida albicans and Candida tropicalis) with some compounds showing bacteriostatic and fungicidal activity. The minimal inhibitory concentration (MIC90) of HnL against Mycobacterium tuberculosis is also reported, with H2L2 and H3L4 showing very high activity (MIC90 < 0.6 mu g/mL). The ability of the compounds to bind bovine serum albumin (BSA) and DNA is evaluated for H3L4 and [Zn-2(L-4)(CH3COO)] (4), both showing high binding constants to BSA (ca. 106 M 1) and ability to bind DNA. Overall, the reported compounds show relevant antitumor and antimicrobial properties, our data indicating they may be promising compounds in several fields of medicinal chemistry.

The carbonylative Suzuki cross-coupling of 2-bromopyridine with various boronic acids to prepare unsymmetrical arylpyridine ketones has been carried out using palladium/N-heterocyclic carbene complexes as catalysts prepared in situ. The selectivity and the rate of these reactions are highly dependent on the conditions, i.e., nature of the palladium catalyst precursor, solvent, temperature and CO pressure. The main side-products arise from direct, non-carbonylative cross-coupling. Under the optimum conditions, arylpyridine ketones are recovered in high yields (60-88%). The antibacterial activities of the corresponding benzimidazole salts 2 were tested against Gram positive and negative bacteria using the agar dilution procedure, and their IC50 values have been determined.

Herein we report, a mononuclear, highly fluorescent zinc(ii) complex Zn(L)(N-3)(H2O) (1) that was prepared by an easy one pot method, in which the tridentate Schiff base ligand (E)-4-((2-(dimethylamino)ethylimino)methyl)-5-(hydroxymethyl)-2-methylpyridin-3-ol (HL) was generated in situ. The compound is characterized by various spectroscopic techniques, and its structure was determined by single crystal X-ray diffraction studies. DFT calculations were used to understand the electronic structures of the ligand and the complex, and TD-DFT calculations were performed to interpret the nature of the electronic transitions observed in their UV-vis spectra. In the complex, Zn(II) is found to be penta-coordinated with one azide ligand, an aqua ligand and a monoanionic tridentate N,N,O-donor ligand. In an aqueous methanol (1:9 by volume) solution, at the physiological pH (0.01 M Tris-HCl buffer, pH 7.4), compound 1 exhibits an intense greenish blue fluorescence (lambda(ex) 390 nm, lambda(em) 462 nm), whose intensity is about 17-fold stronger than that of the free ligand. Compound 1 is found to show significant DNA binding activity. The pyridoxal appended tridentate ligand can be used for the bio-imaging of Zn(II).
