- Abstract
The rare‐earth metal complexes Ln(L1)[N(SiHMe2)2](thf) (Ln=La, Ce, Y; L1=N,N′′‐bis(pentafluorophenyl)diethylenetriamine dianion) were synthesized by treating Ln[N(SiHMe2)2]3(thf)2 with L1H2. The lanthanum and cerium derivatives are active catalysts for the hydrosilylation of benzophenone derivatives with HN(SiHMe2)2. An amine‐exchange reaction was revealed as a key step of the catalytic cycle, in which Ln−Si−H β‐agostic interactions are proposed to promote insertion of the carbonyl moiety into the Si−H bond.
