The author of 《Synthesis of bis(aryloxy)fluoromethanes using a heterodihalocarbene strategy》 were Recsei, Carl; Barda, Yaniv. And the article was published in Beilstein Journal of Organic Chemistry in 2021. Reference of Ethylbromofluoroacetate The author mentioned the following in the article:
A simple and new procedure was developed for the construction of a bis(aryloxy)fluoromethane moiety I and ROCH(F)OR [R = 4-O2NC6H4, 2,5-di-ClC6H4], for which no existing method was available. The results came from multiple reactions, including the reaction of Ethylbromofluoroacetate(cas: 401-55-8Reference of Ethylbromofluoroacetate)
Ethylbromofluoroacetate(cas: 401-55-8) is a member of organofluorine compounds. Organofluorine compounds, which have carbon-fluorine bonds, show unique features such as high thermal and chemical stability, high surface activity, no light-absorbing ability, high pharmacological effect, and so on. Owing to their specific characters, they are indispensable chemicals for industry and our daily lives.Reference of Ethylbromofluoroacetate
