AbstractThe substrate scope and mechanistic insight of the thermal-induced 1,3- and 1,5-sulfonyl migration reactions of various sulfonamides have been investigated. The results indicate that both N-arenesulfonylphenothiazines and N-arenesulfonylphenoxazines can undergo 1,3- and 1,5-sulfonyl migrations to afford the corresponding aryl sulfone derivatives in modest regioselectivities and yields under
