Ruthenium(II) carbonyl complexes containing tetradentate Schiffbases

Ruthenium(II) carbonyl complexes of general formula [Ru(CO)(B)(L)] [where B = PPh3, pyridine (py), piperidine (pip); L = the dianionic tetradentate Schiff bases derived from the condensation of acetylacetone or benzoylacetone with ethylenediamine, propylenediamine or trimethylenediamine] have been synthesised by reacting [RuHCl(CO)(PPh3)2(B)] (B = PPh3, py or pip) with bis(acetylacetone)ethylenediimine, bis(acetylacetone)propylenediimine, bis(acetylacetone)trimethylenedi- imine, bis(benzoylacetone)ethylenediimine, bis(benzoylacetone)propylenediimine or bis(benzoylacetone)trimethylenediimine. The complexes were characterised onthe basis of elemental analyses, i.r., electronic and 1H- and 31P{1H}-n.m.r. spectral studies. This revised version was published online in June 2006 with corrections to the Cover Date.     

Nickel(II) thiosemicarbazone complex catalyzed Mizoroki–Heck reaction

Convenient synthesis of a new square planar nickel(II) naphthaldehyde thiosemicarbazone complex has been described. The composition of the complex has been established by elemental analysis, spectral methods, and single crystal X-ray crystallography. The new complex acts as an active homogeneous catalyst for the Mizoroki–Heck reaction of electron deficient (activating) and electron rich (deactivating) aryl bromides with various olefins under optimized conditions.
