Photolysis of compounds containing an o-nitroarylthio-substituent

Abstract

The photolysis of a number of compounds containing an o-nitroarylthio-substituent has been investigated. Decarboxylation occurs in certain carboxylic acid derivatives and the mechanism of these reactions is considered. In contrast to its thermolysis, photolysis of N-(o-nitrophenylthio)aniline provides 4′-anilinoazobenzene-2-sulphinic acid in moderate yield.
