Abstract

Reactions of the bis(phosphinimino)methane CH2(Ph 2PNSiMe3)2 with the zinc dihalides ZnCl 2 and ZnI2 afforded the corresponding bis(phosphinimino) methane complexes [(Me3SiNPPh2)2CH 2ZnCl2] (1) and [(Me3SiNPPh2) 2CH2ZnI2] (2). In contrast, treatment of CH2(Ph2PNSiMe3)2 with ZnPh 2 in toluene gave the bis(phosphinimino)methanide complex of [(Me3SiNPPh2)2CHZnPh] (3). Further reaction of 3 with the heterocumulenes di(p-tolyl)carbodiimine and diphenyl ketene resulted via a nucleophilic addition of the methine carbon atom of the CH(Ph2PNSiMe3)2- ligand to the heterocumulenes in a C-C bond formation. New tripodal phenyl zinc complexes of composition [(Me3SiNPPh2)2CH)(p-Tol)NC-N(p- Tol)ZnPh] (4) and [(Me3SiNPPh2)2CH)(Ph 2CC-O)ZnPh] (5) were obtained. Â© 2010 The Royal Society of Chemistry.
