Photolysis of 2-fluoro-2′,5′-dimethyldiphenylamine 1a, in ethanol with a medium-pressure mercury lamp, gave a mixture of 1,4-dimethylcarbazole 7 (53%), 8-fluoro-1,4-dimethylcarbazole 2(11%) and 6-ethoxy-2-fluoro-2′,5′-dimethyldiphenylamine 8(19%). Photolysis of 4-fluoro-2′,5′-dimethyldiphenylamine 1b gave 6-fluoro-1,4-dimethylcarbazole 25 (35%) and 1,4-dimethylcarbazole 7(47%).
