Diimide - Wikipedia
Diimide, also called diazene or diimine, is a compound having the formula HN=NH. It exists as two geometric isomers, E (trans) and Z (cis). The term diazene is more common for organic derivatives of diimide. Thus, azobenzene is an example of an organic diazene.
Reductions with diimide - Wikipedia
Reductions with diimide are a chemical reactions that convert unsaturated organic compounds to reduced alkane products. In the process, diimide (N. 2H. 2) is oxidized to dinitrogen. [1] Introduction. In 1929, the conversion of oleic acid to stearic acid in …
