由溴化3-三甲基硅基丙-2-炔基二异丁基碲与2,2,6,6-四甲基哌啶锂(LiTMP)反应生成的二异丁基碲三甲基硅基丙炔叶立德与羰基化合物反应,以良好至优异的产率得到主要为顺式三甲基硅基乙炔基环氧化物。
Diisobutyltelluronium trimethylsilylpropynyl ylide, generated from 3-trimethylsilylprop-2-ynyldiisobutyltelluronium bromide with lithium 2,2,6,6-tetramethylpiperidide (LiTMP), reacts with carbonyl compounds to afford predominately cis-trimethylsilylethynyl epoxides in good to excellent yields.
