Air- and light-stable electrophilic difluoromethylating reagents, S-(difluoromethyl)-S-phenyl-S-(2,4,6-trialkoxyphenyl) sulfonium salts were successfully developed, and the introduction of intramolecular hydrogen bonds plays a crucial role for the stabilities and reactivities of these reagents. C-selective difluoromethylation of a broad range of β-ketoesters and malonates proceeded smoothly under mild

A new, stable and scalable reagent for deuteriodifluoromethylthiolation (deuterated N-difluoromethylthiophthalimide, PhthSCF2D) has been developed. This reagent can be applied for the photocatalytic radical deuteriodifluoromethylthiolation of various olefins and aldehydes (30 examples). Meanwhile, it can achieve the electrophilic deuteriodifluoromethylthiolation of a series of electrophilic substrates
已开发出一种新的、稳定且可扩展的氘代二氟甲基硫醇化试剂(氘代N-二氟甲基硫代邻苯二甲酰亚胺,PhthSCF 2 D)。该试剂可用于各种烯烃和醛的光催化自由基氘二氟甲基硫醇化反应(30个例子)。同时,它可以实现一系列亲电底物的亲电氘代二氟甲基硫醇化,包括富电子芳烃、芳基/乙烯基硼酸、炔烃、胺、硫醇和β-酮酯(22个例子)。使用 PhthSCF 2 D 作为试剂,一些复杂的分子也可以用于自由基和亲电氘代二氟甲基硫醇化。
