Abstract
The photoreduction of the eosin analogue (1; R = H) by tribenzylamine under anaerobic conditions is found to produce a high yield of the cross-coupled product (3; R = H) which readily reoxidises to the starting dye. The formation of (3; R = H), which is considered to take place in the initial solvent cage, has implications for earlier kinetic studies on the photoreduction of related dyes.Keywords
