摘要

Abstract Reactions of dichlorodivinylsilane (2) and LitBu in a molar ratio 1/1 and 1/2 lead to highly reactive intermediates, which can be trapped by suitable reagents. In the presence of trimethylmethoxysilane, norbornadiene, anthracene and diphenylacetylene, products are formed that provide evidence for the intermediate formation of both the neopentylsilene H 2 C= CH (Cl) Si= CHCH 2 tBu (3) and the 2-silaallene tBuCH 2 CH= Si= CHCH 2 tBu (4). ...
