Dithiafulvenylphosphine as P- and P,S-ligand towards metal carbonyl fragments
摘要:
The ability of the dithiafulvenylphosphine ( P-DTF) to react as a monodentate ( P) or a bidentate ( P, S) ligand with metal carbonyl complexes such as Mo(CO)(6) and MnBr(CO)(5) is presented. A series of metal carbonyl complexes are synthesised and characterised by IR, H-1 NMR and P-31 NMR spectroscopy. X-ray crystallographic analyses on the Mo( CO)(5)(P-DTF) and Mo(CO)(4)( P, S-DTF) complexes are reported together with the structural investigations on the dithiafulvenes precursors. The electrochemical properties of the various complexes investigated by cyclic voltammetry are discussed. (C) 2008 Elsevier B. V. All rights reserved.
