  α,α-Difluoro-α-phenylsulfanylmethyl carbanion equivalent: a novel gem-difluoromethylenation of carbonyl compounds

  摘要：

  alpha,alpha-Difluoro-alpha-phenylsulfanyl-alpha-trimethylsilylmethane (PhSCF2SiMe3) has been demonstrated as an alpha,alpha-difluoro-alpha-plhenylsulfanylmethyl carbanion equivalent. gem-Difluorophenylsulfanylmethylation of carbonyl compounds has been successfully achieved by using PhSCF2SiMe3 in the presence of TBAF in THE The adducts have been converted to the corresponding gem-difluoroalkenes by a novel pyrolytic and/or FVP elimination of the beta-hydroxy-alpha-phenyisufinyl derivatives under reduced pressure.

  prepared, and their relative reactivity towards aldehydes, ketones, and imines was investigated. Compared to the former developed (phenylchalcogen)difluoromethylation reagents, these reagents are relatively easily available and more atom-economical in fluoroalkylation reactions. It was found that the efficient nucleophilic (phenylchalcogen)difluoromethylation of aldehydes, ketones, and imines could be

  制备了一系列含硫，硒和碲的（苯基硫属元素）二氟甲基化试剂PhSCF 2 H（1a），PhSeCF 2 H（1b）和PhTeCF 2 H （1c），它们对醛，酮，对亚胺进行了调查。与以前开发的（苯基硫属元素化物）二氟甲基化试剂相比，这些试剂相对容易获得，并且在氟代烷基化反应中更经济。发现用1a - 1c可以实现醛，酮和亚胺的有效亲核性（苯硫族元素）二氟甲基化。试剂1a和1b与羰基化合物和亚胺的反应活性比1c高，并且PhOCF 2 H（1d）无法进行类似的氟烷基化反应。

  Direct nucleophilic gem-difluoro(phenylsulfanyl)methylation of carbonyl compounds has been achieved by use of difluoro(phenylsulfanyl)methane (PhSCF2H) and the phosphazene base P4-tBu in THF. Non-enolizable aldehydes and ketones are suitable substrates to undergo nucleophilic gem-difluoro(phenylsulfanyl)methylation, providing α-gem-difluoromethylated adducts in good yields. In addition, this methodology

  通过在 THF 中使用二氟（苯硫基）甲烷 (PhSCF2H) 和磷腈碱 P4-tBu，已经实现了羰基化合物的直接亲核二氟（苯硫基）甲基化。不可烯醇化的醛类和酮类是适合进行亲核钆-二氟（苯硫基）甲基化的底物，以良好的产率提供 α-gem-二氟甲基化加合物。此外，该方法也适用于环状酰亚胺和酸酐。
• Nucleophilic difluoro(phenylsulfonyl)methylation of carbonyls with PhSO2CF2H reagent in the presence of in situ generated substoichiometric amount of base

  The reactions between carbonyl compounds and PhSO2CF2H using substoichiometric amount of base in situ generated from N(TMS)(3) and catalytic amount of Me4NF have been investigated. It is found that both enolizable and non-enolizable aldehydes are suitable substrates to undergo nucleophilic difluoro(phenylsulfonyl)methylation. Compared to the previously reported trifluoromethylation of carbonyls with CF3H under the similar reaction conditions, the unique reactivity of PhSO2CF2H is attributed to its higher acidity than CF3H and the reversibility of its addition reaction with ketones under basic conditions.
