G. Verardo et al., NEW EXPERIMENTS IN THE REDUCTIVE N-ALKYLATION AND N-PERALKYLATION OF AROMATIC-AMINES, Synthetic communications, 24(5), 1994, pp. 609-627
Some secondary and primary aromatic amines were variously N-alkylated
and N-peralkylated by the aldehyde-sodium borohydride procedure in aci
dic aqueous solution. The procedure lends itself to the alpha-mono and
alpha,alpha'-dideuterium labelling of the new N-substituent(s).
