摘要

A series of crowded olefins were prepared in high yield by the one-pot reaction of in situ generated lithium alkoxides, formed from hindered ketones and alkyllithiums, with thionyl chloride. The prepared olefm are generally inaccessible by either the Wittig reaction or using Grignard reagents because of predominant electron-transfer reduction of the hindered ketones.
