1,7-Dimethylchrysene. Photocyclisation of 1,6-diarylhexa-1,3,5-trienes
Abstract
1,7-Dimethylchrysene has been synthesised from 1,5-diacetylnaphthalene and by photocyclisation of 1,6-di-(o-tolyl)hexa-1,3,5-triene. Irradiation of 1-(2-naphthyl)-6-phenylhexa-1,3,5-triene did not lead to the expected benzo[c]chrysene or naphth[2,1-a]anthracene.
