debromination of vicinal dibromo compounds to generate alkenes usually requires harsh reaction conditions and the addition of catalysts. Just recently the visible‐light‐induced debromination of vicinal dibromo compounds emerged as a possible alternative to commonly used methods, but the substrate scope of this reaction is limited and a photocatalyst is necessary for the successful conversion of the starting
邻位二溴化合物的脱溴反应生成烯烃通常需要苛刻的反应条件和催化剂的添加。就在最近,可见光诱导的邻二溴化合物的脱溴已成为常用方法的一种可能替代方法,但该反应的底物范围有限,光催化剂对于成功转化起始化合物是必需的。据报道,用碱活化的汉茨sch酸酯作为光敏剂,无催化剂的可见光诱导的邻溴二溴化合物的脱溴作用。该方法具有广泛的底物范围和广泛的功能组兼容性。
