摘要

Abstract: The lithium alkoxides of benzylic, allylic, and simple alkyl alcohols were allowed to react with chloroform in the presence of t-BuOLi in THF-hexane to give, in 32-91% yields, dichloromethylcarbinols, which were produced by the insertion of dichlorocarbene into the a CH bond of alkoxides but not by the Wittig rearrangement of carbanions of alkyl dichloromethyl ethers. The enhanced reactivity toward dichlorocarbene of the a CH bond ...
