The thiyl-radical induced fragmentation of alkenyl epoxy silanes has been found to afford α-trimethylsilyl aldehydes as the immediate products. These may be isolated, rearranged to trimethylsilyl dienol ethers, or converted to 1,3-dienes with high stereoselectivity.
已经发现,
硫代烷基自由基诱导的烯基环氧
硅烷的断裂提供α-三甲基甲
硅烷基醛作为直接产物。这些可以分离,重排成三甲基甲
硅烷基二烯醇醚,或以高的立体选择性转化为1,3-二烯。
