Acyl Complexes of Ni(II): Dialkyldithiocarbamate Derivatives

摘要

The synthesis and spectroscopic properties of some new acyls of Ni(II) of formula Ni(COR)(S2CNR#x2032;2)(PMe3) (R=Me3- SiCH2, Me2PhCCH2; R#x2032;=Me, Et, i-Pr) are described. Infrared and1Hnmr studies show a square planar structure for the complexes with a bidentate dithiocarbamate ligand. The new acyls undergo dynamical behaviour in solution and participate in carbon monoxide exchange reactions with NiRCI(PMe3)2complexes to give NiR-(S2CNR#x2032;2)(PMe3) and Ni(COR)CI(PMe3)2.
