摘要:
AbstractThe iminophosphorane Ph2P(CH2Py)(NSiMe3) (Py = NC5H4) is deprotonated at the Cα‐position in a reaction with [M{N(SiMe3)2}2] (M = Fe2+, Zn2+) to give metallaspirocycles in which the metal cations are N,N‐chelated by the ring‐ and imino‐nitrogen atoms of both monoanionic ligands. The molecular structures of [M{Ph2P(CHPy)(NSiMe3)}2] [M = Fe (1), Zn (2)] are discussed and general trends in the bonding of the [Ph2P(CHPy)(NSiMe3)]− anion on metal coordination are deduced.
