secondary amines. Further development of the reductive monoalkylation reaction provided conditions that facilitate conversion of a range of different nitro aryls in one-pot to the corresponding secondary benzyl amino aryls in mostly good to excellent yields. This is accomplished by using hydrogen (1 atm) over Pd/C (10%) as reducing agent and benzaldehyde as the benzyl source combined with a stepwise

A range of different nitroaryls were converted in one-pot to the corresponding secondary alkyl amino aryls in good to excellent yields by using aldehydes as alkyl source and hydrogen over Pd/C (10%) as reducing agent. In all examples, but one, the secondary amine was the sole alkylation product isolated. When formaldehyde was used as the alkyl source, substantial amount of the corresponding tertiary
