Difluoromethylation of the activated X-H bond (X = N, O and S) and aliphatic thiols, and gem-difluorocyclopropenation of alkynes with difluorocarbene generated in situ from difluoromethylene phosphobetaine (Ph3P(+)CF2CO2(-)) by decarboxylation occurred smoothly without the presence of any base or other additives.
活化的X-H键（X = N、O和S）以及脂肪族硫醇的二氟甲基化，以及通过二氟亚甲基膦甜菜碱（Ph3P(+)CF2CO2(-)）脱羧原位生成的二氟卡宾与炔烃的偕二氟环丙烷化反应，在没有任何碱或其他添加剂的情况下顺利发生。
