摘要
Title cpds. are of formula (I):- (where X = H, CH3 or C6H5, R = -COOY, -COOC6H5 or -CN, Y = 1-4C alkyl with the proviso that when X = H, R is not -COOY or -CN). The cpds. are prepd. by bromination of the corresponding allylic compound using N-bromosuccinimide in the presence of a free radical donor.
