Abstract

Substituted diazenes react with zerovalent nickel phosphine complexes to form Π complexes or to eliminate dinitrogen to form nickel(II) species. Possible alternative mechanisms for the photochromic behavior of an azobenzene Π complex are suggested. Several cyano- and alkyl-substituted diazenes have been shown to eliminate dinitrogen and oxidatively add to the Ni(0) complexes. Evidence is presented to suggest that oxidative addition takes place through a Π intermediate. A new complex of bis(p-methylbenzoyl)diazene exhibits a fluxional behavior between square-planar and tetrahedral coordination about the nickel atom.
