N-(1H)-Tetrazole sulfoximines are readily available by addition of sodium azide to the corresponding N-cyano derivatives in the presence of ZnBr 2. The use of these N-(1H)-tetrazoles as intermediates in the synthesis of other N-heterocyclic sulfoximines is demonstrated.

Iodinane- and metal-free synthesis of N-cyano sulfilimines: Novel and easy access of NH-sulfoximines
The synthesis of W-cyanosulfilimines can readily be achieved by reaction of the corresponding sulfides with cyanogen amine in the presence of a base and NBS or l2 as halogenating agents. Oxidation followed by C-N bond cleavage affords synthetically useful WH-free sulfoximines.
