Diimide - Wikipedia
网页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
网页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 the presence of hydrazine was observed. [2] .
11.5: Hydrogenation with Diimide - Chemistry LibreTexts
网页In practice, diimide is generated as it is needed in the presence of the compound to be hydrogenated. There are various ways to do this, but one of the simplest methods is dehydrogenation of hydrazine with oxidizing agents such as atmospheric oxygen or hydrogen peroxide:

Reduction with Diimide - Organic Reactions
网页In this chapter the use of the term “diimide” implies cis-diimide as the reducing agent. The energy barriers for the disproportionation of cis – with cis -, and cis – with trans -diimide are calculated to be 19.3 and 23.8 kcal per mole, considerably smaller than the barriers for hydrogen transfer to a carbon carbon double bond.
