carbonyl-activated methylene and methyl compounds exhibiting no bromo or diazo substituents could be also transformed into dithioesters by the CAT reaction. The structure of three dithioesters was corroborated by X-ray structural analyses. Supplemental materials are available for this article.

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.
由1,5-二乙酰基萘并通过1,6-二-(邻甲苯基)六-1,3,5-三烯的光环化反应合成了1,7-二甲基丙烯。辐照1-(2-萘基)-6-苯基己-1,3,5-三烯不会导致预期的苯并[ c ] ch或萘[2,1- a ]蒽。
