40.7.1.1.22 Method 22: 1,2-Dialkylhydrazines by Reduction of Dialkyldiazenes

DOI: 10.1055/sos-SD-040-00813

Rademacher, P., Science of Synthesis, (2009) 40, 1187.

Dialkyldiazenes ‌185‌ (azo compounds) can be converted by formal addition of hydrogen into the corresponding 1,2-dialkylhydrazines ‌186‌ (‌Scheme 85‌). This method is of minor synthetic importance since dialkyldiazenes are usually generated by oxidation of 1,2-dialkylhydrazines. However, some compounds have been obtained in this way by catalytic hydrogenation, reduction with zinc in sodium hydroxide, hydrazine hydrate in the presence of Raney nickel, or sodium amalgam.[‌113‌,‌196‌]
