Several aromatics, 9,10 dihydroanthracene(DHA), 9,10 dihydrophenanthracene(DHP), acenaphthene(ACE) and dibenzyl(DB) were taken as the model compounds to react with N bromosuccinicimide (NBS) in benzene at room temperature and in normal atmosphere.

• 以 9；1 0 -二氢蒽 ( DHA)、9；1 0 -二氢菲 ( DHP)、苊 ( ACE)和联苄 ( DB)等多环芳烃为模型化合物 ；室温常压下 ；在苯溶剂中与 N-溴代丁二酰亚胺 ( NBS)进行了光化学脱氢反应实验 .
