A copper(I)-catalyzed interrupted dominoreaction of 2-azido sulfoximines with 1-iodoalkynes affords fused triazolyl-containing benzothiadiazine-1-oxides in good to excellent yields. The substrate scope is broad and the functional group tolerance high. Mechanistic studies suggest a reaction pathway via copper π-complexes and a consecutive oxidative coupling of a relevant iodinated triazole as intermediate
