title: Mass spectrometric behaviour of pentachlorophenyl beta-carbonylenolate phosphino nickel(II) complexes: An example of thermal generation of a nickel(III) species.
abstract: The mass spectral behaviour of pentachlorophenyl beta-carbonylenolate phosphino nickel(II) square planar complexes has been investigated under electron impact (EI) and field desorption (FD) conditions. The fragmentation has been interpreted on the basis of the B/E linked scans and mass-analysed ion kinetic energy (MIKE) techniques. The acetylacetonate diphenylphosphino complex was found to undergo a solid state reaction in the probe, which led to the generation in situ of a nickel(III) chloro complex. Careful control of instrumental conditions and computer-assisted EI measurements made it possible to characterize the addition products as [NiCl(C(6)Cl(5))(AcAc)PPh(2)Me] and to propose a mechanism for its solid state generation.
