Primary alkyl chlorides are quantitatively converted to their corresponding bromides in the presence of ethyl bromide, N-methyl-2-pyrrolidinone, and a catalytic amount of metal bromide. A variety of chlorides can be converted. Selective functionalization at bromine of several primary bromochloroalkanes was studied in conjunction with the chloride-bromide conversion for multistep syntheses. Methods
在乙基溴、N-甲基-2-吡咯烷酮和催化量的金属溴化物存在下,伯烷基氯被定量转化为其相应的溴化物。可以转化多种氯化物。结合多步合成的氯 - 溴化物转化,研究了几种主要溴氯烷烃的溴选择性官能化。介绍了辛基卤化物系列中氯化物、溴化物和碘化物之间的卤素交换方法。
