Synthesis and Transformation of [Difluoro(phenylseleno)methyl]- trimethylsilane
摘要:
[GRAPHIC]A novel and efficient strategy was developed to synthesize [difluoro(phenylseleno)methyl]trimethylsilane (PhSeCF2-TMS, 2), which was further utilized as a nucleophilic difluoromethylating reagent to incorporate the difluoro(phenylseleno)methyl (PhSeCF2) group into carbonyl compounds in good yields. The resulting PhSeCF2-containing alcohols 3 could be conveniently converted into corresponding difluoromethyl alcohols 4 by a radical deselenylation.
