Novel rearrangements of N- and α-halogeno derivatives of S-aryl-S[(1,2-benzisoxazol-3-yl)methyl]sulphiximides to the corresponding N-sulphinylimines
Abstract
The title N-and α-halogno-sulohoximides (1) and (2) undergo base-induced rearrangement reactions to give the correspondingN-sulphinylimines (3), suggesting the intermediacy of a three-membered cyclic sulphoximide (4) with an endocyclic SN moiety.
