Irradiation of the amino-4H-1,2,3-triazoles (λ ≥ 280 nm) affords molecular nitrogen and 3-amino-2H-azirines in high yields. As shown on the basis of spectroscopic evidence, the photoproduct of a exists exclusively as 3-amino-2H-azirine a rather than in an

An easy synthesis for the 1,3-thiazol-5(4H)-thiones 5, a class of heterocycles which have hitherto only been available with difficulty, is described.Reaction of 3-amino-2H-azirines 25 with thiocarboxylic acids at 0 deg yields monothiodiamides of type 20 (Scheme 6) which, on treatment with Lawesson reagent at 100 deg, undergo thiation and cyclization to give 5 in good yield.
