Strategies for the one-pot formation of secondary aryl amines from the corresponding nitro aryls by utilizing reductive amination procedures are discussed. The extension of this chemistry where a Suzuki–Miyaura cross-coupling is conducted between a boronic acid and bromonitrobenzene prior to the reductive amination in one-pot is also presented.
Key words
one pot - Suzuki–Miyaura cross-coupling - reductive monoalkylation - biaryl - secondary amine
