Abstract
5-Phenylhepta-1,3Z,5E-triene, the sole product obtained from irradiation of 6-methyl-1-phenylcyclohexa-1,3-diene, is photoisomerized to the (3Z,5Z)-triene by direct irradiation and to the (3E,5E)- and (3E,5Z)-trienes by triplet excitation; 2-methyl-6-phenylocta-2,4Z,6E-triene, obtained from 5,5,6-trimethyl-1-phenylcyclohexa-1,3-diene, behaves similarly.Keywords
