and efficient bromination of aniline, aniline derivatives, and analogs have been developed. Forty three examples were given and the highest yield reached was 98%. Different substrates including substituted aniline, pyridin-amine, N-substituted aniline, N,N-disubstituted aniline, N-phenyl-amide, N-phenyl-sulfonamide, and nitrogen-containing heterocycles were all reactive and selectively generated desired
摘要 已开发出一种简单有效的苯胺、苯胺衍生物和类似物的溴化方法。给出了43个例子,最高产率为98%。包括取代苯胺、吡啶胺、N-取代苯胺、N,N-二取代苯胺、N-苯基-酰胺、N-苯基-磺酰胺和含氮杂环在内的不同底物都具有反应性并选择性地生成所需的溴代产物。该方法可用于合成药物中间体和喹喔啉衍生物。图形概要
