The Insertion of Terminal Phosphinidene Complexes into the BH Bond of Amine and Phosphine Boranes

Abstract

Push–pull complexation: Transient terminal phosphinidene complexes [RP[BOND]W(CO)5] insert at 110 °C into the B[BOND]H bonds of L[BOND]BH3 (L = Et3N, Ph3P; see scheme). The reaction is probably driven by an interaction between the nucleophilic boron and the electrophilic phosphorus
