Castrica, Luca; Fringuelli, Francesco; Gregoli, Luisa; Pizzo, Ferdinando; Vaccaro, Luigi (CEMIN-Dipartimento di Chimica, Universita di Perugia, Perugia I-06123, Italy). Journal of Organic Chemistry, 71(25), 9536-9539 (English) 2006 American Chemical Society.Some commonly used reagents like 41608-07-5 and 18402-83-0 are used in this experiment. CODEN: JOCEAH. ISSN: 0022-3263. DOCUMENT TYPE: Journal CA Section: 21 (General Organic Chemistry) Amberlite IRA900N3 is an excellent organocatalyst for the azidation of a,b-unsatd. ketones with trimethylsilyl azide under solvent-free conditions. By avoiding the use of metallic species and of the org. reaction medium, the procedure is a green tool for the prepn. of b-azido ketones under mild conditions with yields from good to excellent. The catalyst can be recovered and re-used with no loss of its efficiency. .
