- The action of bromine (acetic acid or chloroform) on (I) gives a resinous mixture (bromination of methyl methylen and hydroxy of I). (I) is also hydrolized (TsOH) to 1,1 diphenyl-1 buten-3 one, which adds TBABr3 only on the double bond 1. and bromine both on the methyl and on the double bond (yield < 20%)
