Abstract

Treatment of Cp*(CO)2W(NCMe)Me (Cp* = η5-C5Me5) with HSiR3 (R = Et, p-Tol) afforded N-silylated η2-iminoacyl tungsten complexes Cp*(CO)2W{κ2(C,N)-C(Me)= N(SiR3)} (1a, R = Et; 1b, R = p-Tol). Analogous reactions in the presence of excess acetonitrile for a prolonged reaction time led to the formation of five-membered metallacycles Cp*(CO)2W{κ2(C,N)-C(Me)=N-C(Me) =N(H)} (2) and Cp*(CO)2W{κ2(C,N)-C(CH 2SiR3)=N-C(Me)=N(H)} (3, R = p-Tol) through a C-N coupling of nitrile molecules and migration of a silyl group.
