excited state 2-arenesulfanamido-2-cyclohexenones lead to a very efficient desulfonation reaction and to migration of the aryl substituent. A wavelength effect 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
当以它们的三重激发态激发时,2-芳烃磺酰胺基-2-环己烯酮导致非常有效的脱磺反应并导致芳基取代基的迁移。观察到直接照射对脱硫产物的波长影响。此外,在254nm处,浓度效应和大于1的量子产率表明涉及自由基链成分。考虑到芳基迁移的分子内特性,讨论了该反应的机理。
