title: Cerium-Catalyzed Hydrosilylation of Acrylates to Give α-Silyl Esters.
abstract: The homoleptic organocerium complex Ce{C(SiHMe2)3}3(1) reacts with B(C6F5)3to produce the zwitterionic bis(alkyl) hydridoborato Ce{C(SiHMe2)3}2HB(C6F5)3(2). NMR and IR spectroscopy and X-ray crystallography indicate that each alkyl ligand contains two bridging Ce↼H-Si interactions in both 1 and 2. Compound 2 serves as a precatalyst for the hydrosilylation of acrylates to give α-silyl esters at room temperature with a turnover number of 2200.
