Abstract

Several fluorophenyl azides were photolyzed with aniline at room temperature. Only pentafluoro and 2, 6-difluorophenyl azides gave asymmetrical fluoroazobenzenes as the major products. These products were generated by singlet N H insertion reaction with aniline followed by oxidation of the resulting aromatic hydrazine.
