reductive methylation of aromatic primary amines with carbonyls and 37% formaldehyde using decaborane in one-pot way gave the corresponding tertiaryamines in high yields. The reaction condition was extended for the reduction of nitroaromatic using decaborane and Pd/C followed by the reductive alkylation and reductive methylation using decaborane to give the corresponding tertiaryamines in high yields.

nitrosation was never observed, but minor amounts of m- and p-nitro amines and/or nitrosamines were formed in some cases. Ring nitration is rather a reaction of the initial substrate than a process occurring on formed nitrosamines. The leaving propensities of the initial N-substituents to yield nitrosamines were in the order benzylmethyl alkyl.
Amines (primary and secondary) were methylated to the corresponding tertiary amineusing 37% formaldehyde and decaborane in methanol at room temperature under nitrogen in high yields.
