difluoromethylation of carbonyl compounds (both enolizable and non-enolizable aldehydes and ketones) has been achieved by using a nucleophilic (phenylsulfonyl)difluoromethylation-reductive desul-fonylation strategy. Difluoromethyl phenyl sulfone acts as a difluoromethyl anion ("CF2H-") equivalent. (C Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005).
通过使用亲核(苯磺酰基)二氟甲基化-还原性脱磺酰化策略,已经实现了羰基化合物(可烯醇化和不可烯醇化的醛和酮)的通用和有效的亲核二氟甲基化。二氟甲基苯砜充当二氟甲基阴离子(“CF 2 H-”)等价物。(C Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)。
