Reactions of halogen(2,4,6-tri-tert-butylphenylimino)phosphine complexes with electrophiles and nucleophiies: abstraction or substitution of the halogen

Abstract

The structure of the first nickel halogeniminophosphine complex, i.e.(PEt₃)₂Ni(X–PNAr)₂(Ar = 2,4,6-tri-tert-butylphenyl); X = Cl is reported; reactions of this and related compounds with AlCl₃ afford the cationic complexes 7–10; the alkyliminophosphine complexes 12 and 13 are obtained by treatment of the chloroiminophosphine complexes 1a and 4a with Grignard reagent.
