Free radical fluoroalkylation of terminal alkenes and alkynes with iododifluoromethanesulfonamides has been successfully achieved. It was found that both the catalytic amount of sodium dithionite (Na2S2O4) and the stoichiometric amount of triethylborane (Et3B)/air can efficiently initiate the current free-radical atom transfer reaction.
端炔和端烯自由基氟烷基化反应已成功实现,使用了碘二氟甲基磺酰胺。研究发现,硫酸钠二硫酸盐(Na2S2O4)的催化量和三乙基硼(Et3B)/空气的化学计量量均能有效引发当前的自由基原子转移反应。
