bromination of diphenylmethane and methyl derivatives with N-bromosuccinimide afforded benzophenone and (polybromomethyl)benzophenones via the hydrolysis of dibromodiphenylmethanes. 1,2-Diphenylethane and p-t-butyl derivative gave dibromostilbenes, while the o-methyl derivative afforded bis(dibromomethyl)dibromodiphenylethane. 10,11-Dihydro-5H-dibenzo[a,d]cycloheptene gave 9-bromodibenzocycloheptenone, which
二苯甲烷和甲基衍生物与 N-溴代琥珀酰亚胺的光热溴化反应通过二溴二苯甲烷的水解得到二苯甲酮和(多溴甲基)二苯甲酮。1,2-二苯基乙烷和叔丁基衍生物得到二溴芪,而邻甲基衍生物得到双(二溴甲基)二溴二苯基乙烷。10,11-二氢-5H-二苯并[a,d]环庚烯得到9-溴二苯并环庚烯酮,它也是在10,11-二氢-5H-二苯并[a,d]环庚烯-5-酮的溴化反应中得到的。
