摘要

β-Trimethylsilyl allenes have been prepared in fair to good yields from allylsilanes by successive dibromocarbene addition and rearrangement of the cyclopropylidenes. In the case of 3, 6-bis (trimethylsilyl) cyclohexa-1, 4-diene, insertion of dibromocarbene occurs in the silicon-carbon bond leading to α-bromobenzyltrimethylsilane.
