1,3-dibromo-5,5-dimethylhydantoin (DBDMH) is a useful and easy to handle reagent for bromination of various aromatic derivatives substituted with electron donating groups. In the presence of trimethylsilyltrifluoromethanesulfonate, DBDMH showed increased reactivity, and in one case, the reaction followed another pathway, suggesting an alternative mechanism.
1,3-二溴-5,5-二甲基乙内酰脲(DBDMH)是一种有用且易于处理的试剂,用于溴化被供电子基团取代的各种芳族衍生物。在存在三甲基甲硅烷基三氟甲磺酸酯的情况下,DBDMH显示出增加的反应性,在一种情况下,反应遵循另一条途径,表明存在另一种机理。
