Effects of Aryl Substituents on Electron-Transfer-Mediated Photochemical Addition of Alcohol to 1,1,2-Triarylcyclopropanes

Direct irradiation of 1,1,2-triarylcyclopropanes in alcohol resulted in the formation of all possible products arising from trimethylene biradicals, while DCB-sensitised irradiation gave a novel "anti-Markownikoff" addition product of alcohol almost exclusively.In order to get insight into the nature and fate of intermediates in the reactions, the effects of nucleophiles and aryl substituents are examined.

Synthesis and Reactions of 1-Thianaphthalenes

Treatment of 1-methyl-4-phenyl-1-thio-2H-chromenium perchlorate (2) with sodium hydride yielded a dimeric compound 4 and two rearrangement products 5 and 6 via unstable 1-methyl-4-phenyl-1-thianaphthalene (3).On heating with potassium hydroxide in ethanol
