  • 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. Coll., 9, 422 (1998):
