摘要:
Samarium diiodide is a catalyst for the reaction of cyclic and acyclic tert-butyldimethylsilyl enoxysilanes with chelating imines. Reaction products are isolated as beta-aminoenoxysilanes instead of beta-aminoketones as previously observed with the corresponding trimethylsilyl enoxysilanes. Several mechanistic pathways are discussed. (C) 2004 Elsevier Ltd. All rights reserved.
