摘要: The reaction of 2-(diphenylphosphanyl)benzeneselenol with Ni(PMe3)4 yielded the hydridonickel(II) complex [Ph2P(C6H4)Se]NiH(PMe3)2 (1). insertion reactions 1 alkynes have been investigated. vinylnickel complexes [Ph2P(C6H4)Se]Ni(CPh=CH2)(PMe3) (2) and [Ph2P(C6H4)Se]Ni(CCH3=CHPh)(PMe3) (3) were obtained by reacting phenylacetylene 1-phenyl-1-propyne 1. nickelacyclopropane [Ph2P(C6H4)Se]Ni[Ph(PMe3)C–CHPh] (4), [Ph2P(C6H4)Se]Ni[(SiMe3)(PMe3)C–CH2] (5) 6 (6A 6B) containing an ylidic ligand diphenylacetylene, (trimethylsilyl)acetylene, 1-phenyl-2-(trimethylsilyl)acetylene molecular structures 1–5 determined single-crystal X-ray diffraction.
