On December 20, 2021, Zhang, Rongyi; Li, Qigang; Xie, Qiqiang; Ni, Chuanfa; Hu, Jinbo published an article.Related Products of 2567-29-5 The title of the article was Difluorocarbene-Induced Ring-Opening Difluoromethylation-Halogenation of Cyclic (Thio)Ethers with TMSCF2X (X=Br, Cl). And the article contained the following:
The ring-opening difluoromethylation-halogenation of cyclic (thio)ethers is reported through a simple strategy relying on carbon-chalcogen bond activation with difluorocarbene. The reaction proceeds through in situ protonation of the previously little-known difluoromethylene oxonium or sulfonium ylide intermediate followed by ring-opening with halide ion to afford halogenated acyclic difluoromethyl (thio)ethers that can then be employed for further elaboration. TMSCF2X (X=Br, Cl) are unique reagents to achieve this synthetic purpose, which serve as both the difluorocarbene source and the halide ion source. The experimental process involved the reaction of 4-(Bromomethyl)-1,1′-biphenyl(cas: 2567-29-5).Related Products of 2567-29-5
