Abstract
The photothermal bromination of diphenylmethane and methyl derivatives with N-bromosuccinimide afforded benzophenone and (polybromomethyl)-b enzophenones via the hydrolysis of dibromodiphenylmethanes. 1,2-Diphen ylethane 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-bromodibenzocyclo-hep tenone, which was also obtained in the bromination of 10,11-dihydro-5H -dibenzo[a,d]cyclohepten-5-one.
