Copper-mediated (phenylsulfonyl)difluoromethylation of propargyl chlorides and alkynyl halides with PhSO2CF2TMS reagent was successfully achieved to give PhSO2CF2-containing allenes and alkynes, respectively. It is believed that the in situ formed PhSO2CF2Cu species is involved in the present (phenylsulfonyl)difluoromethylation reactions.
通过铜介导的(苯磺酰基)二氟甲基化反应,成功实现了对炔丙基氯化物和炔基卤化物的转化,使用的试剂为PhSO2CF2TMS,最终得到含有PhSO2CF2的烯烃和炔烃。研究认为,在此反应中形成的原位PhSO2CF2Cu物种参与了该(苯磺酰基)二氟甲基化反应。
