A procedure for the iodoamination of unfunctionalized olefins tethered to a tosyl-protected NH-group has been developed. The combined use of KI and H2O2 in aqueous medium was effective for the preparation of iodomethyl-substituted nitrogen-containing heterocycles. The selective exo-trig iodocyclization provided 1,2-bifunctional 5-, 6-, and 7-membered cyclic skeletons. In the experiment, the researchers used many compounds, for example, 4-Methylbenzenesulfonamide(cas: 70-55-3Electric Literature of C7H9NO2S)
4-Methylbenzenesulfonamide(cas: 70-55-3) belongs to anime. Reaction with nitrous acid (HNO2), which functions as an acylating agent that is a source of the nitrosyl group (―NO), converts aliphatic primary amines to nitrogen and mixtures of alkenes and alcohols corresponding to the alkyl group in a complex process. This reaction has been used for analytical determination of primary amino groups in a procedure known as the Van Slyke method.Electric Literature of C7H9NO2S
