二碘化钐是环状和非环状叔丁基二甲基甲硅烷基烯氧基硅烷与螯合亚胺反应的催化剂。反应产物分离为β-氨基烯氧基硅烷，而不是如先前用相应的三甲基甲硅烷基烯氧基硅烷观察到的β-氨基酮。几种机制的途径进行了讨论。(C)2004爱思唯尔有限公司保留所有权利。
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.
