Applications

4-Acetamidobenzenesulfonyl azide is used as a hydroazidation catalyst for facile preparation of organoazides. It is used as a reagent for synthesis of: monosaccharide-derived alcohols, a late-stage intermolecular C-H olefination, intramolecular isomuenchnone cycloaddition approach to antitumor agents, rhodium-catalyzed carbene cyclization cycloaddition cascade reaction of vinylsulfonates and Suzuki-Miyaura cross coupling reaction.

Notes

Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Incompatible with strong oxidizing agents.

Diazo transfer agent. Recommended as a safer alternative to tosyl azide for diazo transfer reactions, in the presence of a base, e.g. Et3N or DBU, with active methylene compounds. A further advantage of the reagent is that the by-product sulfonamide is removable by trituration with water: Synth. Commun., 17, 1709 (1987). For illustrative examples, with subsequent cyclization using Rhodium(II)­ acetate, L15152, as a route to highly substituted furans, see: Tetrahedron, 44, 3343 (1988); Org. Synth.
