Photolytic conversion of 1-aryl-1,2,3-triazoles (5) and (14) into the ‘rearranged’ indoles (4) and (15), respectively, provides the first evidence for antiaromatic 1H-azirines, e.g.(8), as reactive intermediates in a photochemical reaction.

provides the first evidence for antiaromatic 1H-azirines as intermediates in a photochemical reaction. Photolysis of the 2-methylnaphthyl′compounds follows a different path: diester (7b) and dinitrile (7d) give high yields of the deeply coloured 9-methyl-1H-benzo[de]quinoline derivatives (25a) and (25b) respectively, the first stable examples of this ring system to be isolated. Photolysis of the nitrile
