摘要

Solutions of several open-chain 1, 2-diazidoethenes were photolyzed to yield 2-azido-2H- azirines, which were identified by NMR spectroscopy at low temperature. On prolonged irradiation or warm-up of the NMR solutions, these heterocycles lost a second molecule of nitrogen to be cleaved into two fragments of cyano compounds. In the case of (Z)-2, 3- diazidocinnamaldehyde, the formation of formyl cyanide was detected by IR spectroscopy ...
