N‐Methyl‐alkylamine können bequem und rasch über die 1,3,5‐Tris(alkyl)‐hexahydro)‐1,3,5‐triazine durch Reduktion mit Zink/Salzsäure bei −5° im Zutropfverfahren gewonnen werden. Die Reinheit (GC) beträgt ∼ 95%.
A simple and efficient method is described for a general synthesis of 4-dialkylamino-5-methoxy-1,2-benzoquinones 3 which involves, in polar solvents, a regioselective (>95%) nucleophilic monosubstitution by a wide range of secondary alliphatic amines on an easily prepared 1,2-quinone 1. Regioselectivity is not observed in the reaction of primary amines with 1, but a further reaction with an alcohol in basic medium allows valorization of the undesirable product.

Conformations and configurations were assigned to several N-Me imines and N-alkyl acetaldimines from analyses of their 60-Mc NMR spectra. All aldimines exist exclusively in the syn configuration. Interpretation of the vicinal and long-range (across 4 and 5 and bonds) spin-spin coupling constants of N-Me aldimines led to the conclusion that I and II are the minimum energy conformations of these compounds

Reaction of a series of primary amines with bis(diphenylphosphinyl) peroxide conveniently leads to N-alkyl-O-diphenylphosphinylhydroxylamines. These compounds rearrange on heating to the thermodynamically more stable N-phosphinylated derivatives, the N-alkyl-N-diphenylphosphinylhydroxylamines (N-alkyldiphenylphosphinohydroxamic acids).
