摘要

事实证明，膦银络合物 (XantPhos)AgBr 是一种廉价且易于获得的催化剂，可用于富电子烯与 CFBr2CO2Na 的溴氟环丙烷化反应。研究表明，先用臭氧分解，再用 NaHSO3 处理，是从未反应的烯烃前体中提纯溴氟环丙烷的有效方法。

(XantPhos)AgBr as a cheap and readily available catalyst for the bromofluorocyclopropanation of electron-rich alkenes

A silver phosphine complex (XantPhos)AgBr proved to be a cheap and readily accessible catalyst for bromofluoro- cyclopropanation of electron-rich alkenes with CFBr₂CO₂Na. Ozonolysis followed by treatment with NaHSO₃ was shown to be an effective protocol to purify gem-bromofluoro- cyclopropanes from unreacted alkene precursors.

期刊介绍： Mendeleev Communications is the journal of the Russian Academy of Sciences, launched jointly by the Academy of Sciences of the USSR and the Royal Society of Chemistry (United Kingdom) in 1991. Starting from 1st January 2007, Elsevier is the new publishing partner of Mendeleev Communications. Mendeleev Communications publishes short communications in chemistry. The journal primarily features papers from the Russian Federation and the other states of the former USSR. However, it also includes papers by authors from other parts of the world. Mendeleev Communications is not a translated journal, but instead is published directly in English. The International Editorial Board is composed of eminent scientists who provide advice on refereeing policy.
