Study of the Synergistic Effect Between Corrosion Inhibitors by Using Fractional Free Volume

The fractional free volumes(FFVs) of the adsorption films formed with different ratios of dipropargyl methoxythiourea imidazoline(DPFTAI) and pyridine quaternary ammonium salt(16BD) were calculated by simulation to determine their synergistic corrosion inhibition effect. The results suggest that the composite corrosion inhibitor at the molar ratio between DPFTAI and 16BD of 4:1 gives the best corrosion inhibition effect. This simulation method to predict the synergistic effect between corrosion inhibitors was further validated by mass loss and electrochemical experiments. This finding delivers valuable understandings of inhibition mechanism of corrosion inhibitors.

Structural, spectral and thermal properties of a supramolecular assembly based on p-phenylenediamine and trichloroacetic acid: A combined experimental and computational study

Single-crystals of the p-phenylenediammonium bis(trichloroacetate) sesquihydrate compound (I) have been grown by slow evaporation method. XRD study showed the presence of two symmetrically independent water sites; one water site is fully occupied while the other one shows partial occupancy (0.5). The new compound has been characterized by FT-IR, Raman and UV-visible spectroscopies. Thermal behavior of (I) has been studied by TGA/DSC analysis. In the structure of (I), the coherence of the 3-D supramolecular assembly is ensured by conventional hydrogen bonds (O-H center dot center dot center dot O and N-H center dot center dot center dot O) and C-Cl center dot center dot center dot pi interactions. Nature and contribution of the different intermolecular interactions that occur in compound (I) were probed through the 3-D Hirshfeld surface and the associated 2-D fingerprint plots. O center dot center dot center dot H/H center dot center dot center dot O interactions (related to the H-bonds) contribute by 30.5% to the total Hirshfeld surface; furthermore, contacts involving chlorine atoms represent ca. 54% of the total surface. Quantum chemical study performed with DFT (B3LYP and HSEH1PBE) methods at 6-311G(++)(d.p) level has permitted calculation of optimized geometry, modes of vibrations, atomic charges, thermodynamic parameters, FMOs and NBOs of the title molecule.

Xantphos-ligated palladium dithiolates: An unprecedented and convenient catalyst for the carbonylative Suzuki-Miyaura cross-coupling reaction with high turnover number and turnover frequency

Xantphos- and dithiolate-ligated macrocyclic palladium complexes as an efficient and stable catalyst for the carbonylative Suzuki-Miyaura cross-coupling reaction have been synthesized. The catalysts were characterized by H-1-nuclear magnetic resonance (NMR), CHNS (carbon, hydrogen, nitrogen, and sulfur) analysis, melting point analysis, and P-31-NMR spectroscopy. Several sensitive functional groups (e.g., -NO2, -F, -Cl, -Br, -NH2, and -CN) on the aromatic ring were well tolerated in the carbonylative Suzuki-Miyaura coupling reaction. The present palladium complexes produce six times higher turnover number (TON) and five times higher turnover frequency (TOF) compared with conventional homogeneous palladium precursors. Maximum TONs in the range of 10(5) to 10(6) and TOF in the range of 10(4) to 10(5) could be generated by a very low amount of catalyst loading (10(-5) mol%).

Bifunctional Ru-loaded Porous Organic Polymers with Pyridine Functionality: Recyclable Catalysts for N-Formylation of Amines with CO2 and H-2

A series of pyridine functionalized porous organic polymers (POPs-Py&PPh3) have been synthesized by polymerizing tris(4-vinylphenyl)phosphane and 4-vinylpyridine. The pyridine moieties in the copolymer materials contribute to CO2 adsorption and promote the subsequent conversion of CO2. The POP supported Ru catalyst (Ru/POP3-Py&PPh3) shows a high catalytic activity (TON up to 710) in the N-formylation of various primary and secondary amines with CO2/H-2, affording the corresponding formamides in good yields (55-95%) under mild reaction conditions. The heterogeneous catalyst can be easily separated from the reaction system and reused for at least eight cycles in the N-formylation of morpholine.

Syntheses, reactivity, structures and photocatalytic properties of mononuclear ruthenium(II) complexes supported by 1,4,7-trime- thyl-1,4,7-triazacyclononane (Me(3)tacn) ligands

Treatment of ruthenium(II) precursor [(Me(3)tacn)Ru(dmso)Cl-2] (Me(3)tacn = 1,4,7-trimethyl-1,4,7-triazacyclononane, dmso = dimethylsulfoxide) (1) with concentrated HCl in the presence of air afforded a ruthenium(III) complex 1(Me(3)tacn)RuCl3 center dot H2O] (2). Reaction of 2, 2,2′-bipyridine or substituted 2,2′-bipyridine, and zinc metal powder in the presence of sodium perchlorate gave the corresponding cationic aquaruthenium(II) complex [(Me(3)tacn)Ru(R-bpy)(H2O)](ClO4)(2) (bpy = 2,2′-bipyridine, R = H, 3; 4,4′-Me-2, 4; 5,5′-Me-2, 5; 4,4′-di-Bu-t, 6). The hydrate ligand in complexes 3 and 5 could be substituted by acetonitrile or pyridine forming complexes [(Me(3)tacn)Ru(5,5′-Me-2-bpy)(CH3CN)](ClO4)(2) (7) and [(Me(3)tacn)Ru(R-bpy)(py)(ClO4)(2) (py = pyridine, R = H (8), R = 5,5′-Me-2 (9), respectively. Interaction of [(Me(3)tacn)Ru(bpy)(H2O)](PF6)(2) with phenylacetylene in methanol afforded a ruthenium-carbene complex [(Me(3)tacn)(bpy)Ru=C(OMe)CH2Ph](PF6)(2) (10). All complexes are well characterized by infrared, UV/Vis, and NMR spectroscopies. The molecular structures of 1, 1 center dot 2H(2)O, 4 center dot 2H(2)O, 7, 8, 9, and 10 have been also established by single-crystal X-ray diffraction. The photocatalysis properties of complexes 3, 5, and 6 for H-2 evolution by water splitting were also investigated in the paper.

In-Depth Study of the Electronic Properties of NIR-Emissive kappa N-3 Terpyridine Rhenium(I) Dicarbonyl Complexes

The structure-properties relationship in a series of carbonyl rhenium(I) complexes based on substituted terpyridine ligands of general formula [Re(kappa N-x-Rtpy)(CO)(gamma)L](n+) is explored by both experimental and theoretical methods. In these compounds, the terpyridine ligands adopt both bidentate (kappa N-2) and terdentate (kappa N-3) coordination modes associated with three or two carbonyls, respectively. Conversion from the kappa N-2 to the ON coordination mode leads to large changes in the absorption spectra and oxidation potentials due to destabilization of the HOMO level of each complex. The absorption profiles of the kappa N-3 complexes cover the whole visible spectra with lower maxima around 700 nm, tailing out to 800 nm, while no emission is observed with Br- as the axial ligand L. When the axial ligand is modified from the native halide to pyridine or triphenylphosphine, the lowest absorption band is blue-shifted by 60 and 90 nm, respectively. These cationic complexes are near-infrared emitters with emission maxima between 840 and 950 nm for the pyridine compounds and 780-800 nm for the triphenylphosphine compounds.
