原始语种摘要: Irradiation of N -aryl O -aryl carbamates has been carried out in H2O/CH3CN (1 : 1 v/v) solutions at λ > 290 nm. When chlorine is on the N -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 and N -arylacetamides (photo-Ritter products), respectively. Unsubstituted N -aryl carbamates slowly undergo photo-Fries reaction.
