Abstract

Abstract Matrix photolysis of 4-quinolyl azide 22 affords 4-quinolylnitrene 21, identified by electron spin resonance (ESR) and infrared (IR) spectroscopy. Minor absorptions assigned to azirene 23 (1741 cm− 1) were also observed. Further photolysis affords strong absorptions at 1902 and 1909 cm− 1 ascribed to the cyclic ketenimine 19 as well as weaker absorptions at 2044 cm− 1 ascribed to the open-chain ketenimine 26 and at 1982 cm− 1 ...
