Abstract

Aryl azides 2 containing alkynyl or alkenyl group as dipolarophile were prepared and thermally decomposed in benzene. Azides 2a-3d gave the corresponding 1,3-cycloadducts, fused-ring l,2,3-triazoles 8a-8d, while bridgehead nitrogen aziridines 9 and 10, were obtained from 3e and 3f, probably via unstable δ2-1,2,3-triazolines.
