The nitration of 3-acetamido, 3-formamido and 3-carbethoxyamino-9-ethylcarbazoles has been studied.Nitration of 3-acetamido-9-ethylcarbazole substituted the 6-position while 3-formamido- and 3-carbethoxyamino-9-ethylcarbazoles gave 4-nitro derivatives.The nitration of three compounds in the 4- and 6-positions was accomplished.Further substitution of 3-acetamido- and 3-carbethoxyamino- derivatives yielded the 4,6,8-trinitro compounds.Assignment of the structures was based on nmr spectral studies and on unequivocal syntheses.
