excited state 2-arenesulfanamido-2-cyclohexenones lead to a very efficient desulfonation reaction and to migration of the aryl substituent. A wavelengtheffect was observed on the desulfonation product from direct irradiations. Furthermore, at 254 nm, a concentration effect and a quantum yield higher than unity indicate that a radical chain component was involved. The mechanism of this reaction is discussed

hexenones; however a desulfonation and aryl migration process can compete in the case of 2-arenesulfonamido-2-cyclohexenones. Furthermore divinylamine and photo-Fries rearrangements are the main reactions with 2-anilino 2-cyclohexnone and 2-benzoylamido 2-cyclohexenone respectively.
