Reaction of 2',6-dimethyl-2-nitrobiphenyl with triethyl phosphite gave 4,5-dimethyl-9-ethylcarbazole besides 4,5-dimethylcarbazole.In this reaction, 4,5-dimethylcarbazole was ethylated by triethyl N-(2',6-dimethylbiphenyl-2-yl)phosphorimidate and diethyl N-(2',6-dimethylbiphenyl-2-yl)phosphoramidate, which arose from a nitrene-intermediate and triethyl phosphite.Analogous ethylations of carbazole with other phosphorimidate and phosphoramidates were investigated.
