On the sulfimidation of benzo[b]thiophene

Benzo[b] thiophene and chloramine-T react in the presence of catalytic amounts of [Cu(NCMe)(4)] BF4 to yield a novel dihydrobenzothiazine arising from a ring- expansion ; if the reaction is conducted in the absence of the copper( I) catalyst no reaction takes place, but the expected sulfimide can be made using [(N-tosylimino) iodo] benzene, PhI=NTs.
