已经开发了在温和条件下进行的重氮化合物的无过渡金属的二氟亚甲基化,并且基于使用TMSCF 2Br作为二氟亚甲基源和四丁基溴化铵(TBAB)作为促进剂。由于二氟卡宾中间体的电子性质和相对稳定性,实现了化学选择性的甲醛卡宾二聚反应。
A transition‐metal‐free difluoromethylenation of diazo compounds that proceeds under mild conditions has been developed and is based on the use of TMSCF2Br as the difluoromethylene source and tetrabutylammonium bromide (TBAB) as the promoter. The chemoselective formal carbene dimerization reaction is achieved owing to the electronic properties and the relative stability of the difluorocarbene intermediate.
