thane has been demonstrated to be a highly versatile gem-difluoromethylene (CF2) building block via the reaction of difluorophenylsulfanylmethyl radical with olefins. gem-Difluoroalkenes and products containing a midchain CF2 group and with manipulatable functionality can be readily synthesized. The first example of a gem-difluoromethylene radical synthon is also reported.
通过二氟苯基硫烷基甲基自由基与烯烃的反应,已证明溴二氟苯基硫烷基甲烷是一种高度通用的宝石-二氟亚甲基(CF 2)结构单元。偕- Difluoroalkenes和含有midchain CF产品2组和可操纵的功能可以被容易地合成。还报道了宝石-二氟亚甲基自由基合成子的第一个例子。
