Palladium(II) complexes with salicylideneimine based tridentate ligand and triphenylphosphine: Synthesis, structure and catalytic activity in Suzuki-Miyaura cross coupling reactions

Square planar palladium(II) complexes of the type [Pd(L)(PPh3)] (1-6) (where L is the dianion of N-(2-mercaptophenyl)salicylideneimine or 5-substituted-N-(2-mercaptophenyl)salicylideneimine or N-(2-mercaptophenyl) naphthylideneimine) have been synthesised from the reactions between [Pd(PPh3)4] and H2L in dichloromethane-ethanol mixture. The new complexes have been characterized by analytical and spectral (electronic, IR, 1H, 13C{1H} and 31P{1H} NMR spectroscopy) techniques. The structures of three complexes (1, 2 and 6) have been solved by single-crystal X-ray diffraction experiments which indicate square planar coordination geometries around palladium(II) by O, N, S and P donor atoms. The palladium(II) complexes (1-6) exhibited good catalytic activity in Suzuki-Miyaura cross-coupling reaction between phenylboronic acid and 4-bromotoluene in N,N-dimethylacetamide at 100 °C. Complex 3 (1 mol%) was found to be the most active and hence was used for probing the scope of possible substrates. Heterocyclic boronic acid and heterocyclic aryl bromides have also been used as substrates to provide heterocyclic biaryls.

NOS donor Schiff base and their nickel(II) complexes: Synthesis, characterization, electrochemical and antimicrobial studies

A series of nickel(II) complexes [Ni(L)(L1)] (1), [Ni(L)(PMDT)] (2) and [Ni(L)(Dien)] (3) have been synthesized with newly synthesized Schiff base derived from 5-bromosalicylaldehyde and 2-aminothiophenol, L = (4-bromo-2-{[(2-sulfanylphenyl)imi

Ruthenium(II) carbonyl complexes containing 'pincer like' ONS donor Schiff base and triphenylphosphine as catalyst for selective oxidation of alcohols at room temperature

Reactions of H2L with [RuHCl(CO)(PPh3)3] in toluene gives [Ru(L)(CO)(PPh3)2] (L = binegative tridentate ONS donor ligand derived from salicylaldehyde/4-substituted salicylaldehyde/2-hydroxy-1-naphthaldehyde and o-aminothiophenol) at room temperature. All the complexes were characterized by elemental analyses and UV-Visible, FT-IR, 1H, 13C and 31P NMR spectroscopic methods. 1H-1H COSY and 1H-31P HMBC spectra of [Ru(L4)(CO)(PPh3) 2] have been studied. 1H-31P HMBC spectrum established the coupling of phosphorus atoms with azomethine proton. The single crystal X-ray analysis of [Ru(L5)(CO)(PPh3)2] revealed that Schiff base ligand is coordinated to the metal center, via dissociation of the two acidic protons, as a dianionic tridentate ONS donor and that ruthenium(II) ion adopts octahedral coordination with the phosphorus atoms in trans-disposition. Ruthenium complexes have been used in conjunction with N-methylmorpholine-N-oxide (NMO) for the catalytic oxidation of various alcohols at room temperature. Benzylic primary and secondary alcohols are oxidized in good to excellent yields, and aliphatic and cyclic alcohols give carbonyl compounds in moderate yields.

Synthesis, characterization and catalytic activity of Fe(III) complexes containing Schiff base and triphenylphosphine ligands

The oxidation of alcohols to carbonyls was investigated by an efficient catalyst system comprising of Fe(III)-Schiff base-triphenylphosphine complex. The complex chloroN-(2-mercaptophenyl)salicylideneiminebis(triphenylphosphine) iron(III) showed higher activity for oxidation of various alcohols under relatively mild conditions.
