The trifluoromethylcarbene (:CHCF3) was found to be conveniently generated from (2,2,2-trifluoroethyl)diphenyl-sulfonium triflate (Ph2S+CH2CF3–OTf), which was successfully applied in Fe-catalyzed cyclopropanation of olefins, giving the corresponding trifluoromethylated cyclopropanes in high yields.
发现三氟甲基卡宾(:CHCF 3)是由(2,2,2-三氟乙基)二苯基-三氟甲磺酸盐(Ph 2 S + CH 2 CF 3 – OTf)方便地生成的,已成功地用于Fe催化的环丙烷丙烷化反应中。烯烃,以高收率得到相应的三氟甲基化的环丙烷。
