The reactiont of boron trichloride or trifluoride with ortho-aryl, -diazoaryl, and -arylazoaryl phenyl azides in benzene at room temperature generally gives fused azoles in high yields.Treatment of 2-nitrophenyl azide with boron trichloride mainly affords chlorinated nitroanilines, whereas with boron trifluoride it gives N-o-nitrophenylaniline.In aromatic solvents at 60 deg C in the presence of boron trifluoride-diethyl ether, 2-azidobiphenyl forms carbazole and 2-(arylamino)biphenyls, the formation of which depends greatly upon the nucleophilicity of the solvent used; however, its pseudo-first-order decomposition rate is slightly greater in benzene than in toluene or m-xylene.Under the same conditions, phenyl azide forms diarylamines.The results suggest that singlet nitrenium ions, arising from the corresponding azidetrihalogenoborane complexes by loss of molecular nitrogen, are generally the reactive intermediates.
