Abstract

Irradiation ofN-arylO-aryl carbamates has been carried out in H2O/CH3CN (1 : 1 v/v) solutions atλ>290 nm. When chlorine is on theN-aryl ring, halogen-substituted products are found. These photoproducts derive from the trapping of the intermediate radical cation by water and, even, by acetonitrile leading to phenols andN-arylacetamides (photo-Ritter products), respectively. UnsubstitutedN-aryl carbamates slowly undergo photo-Fries reaction.
