REACTION OF ORGANIC AZIDES WITH UNSATURATED COMPOUNDS. IX. PRODUCTS FROM REARRANGEMENT OF 1-ARYLSULFONYL-4,4,5-TRIMETHYL-5-ETHOXY-1,2,3-TRIAZOLINES

Ethyl N-arylsulfonyl-2,2-dimethylpropanimidates and N-(1,1-dimethyl-2-ethoxy-2-propenyl)arenesulfonamides are obtained in the reaction of arylsulfonyl azides with 2-methyl-3-ethoxy-2-butene.Thus, the intermediate 1-arylsulfonyl-4,4,5-trimethyl-5-ethoxy-1,2,3-triazolines not only rearrange to the imidates but are also converted into unstable 1-arylsulfonyl-2,2,3-trimethyl-3-ethoxyaziridines, which isomerize to the N-substituted arenesulfonamides.
