Abstract
The ligands on a silicon atom in allylsilanes were found to influence the efficiency of their reaction with ketones in the presence of MnO2. An electron-donating group on silicon provided a promoting effect, ye t the steric effect of a bulky silyl group retarded the addition proce ss. (C) 1998 Elsevier Science Ltd. All rights reserved.
