説明

<jats:title>Abstract</jats:title> <jats:p>The photothermal 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 was also obtained in the bromination of 10,11-dihydro-5H-dibenzo[a,d]cyclohepten-5-one.</jats:p>
