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.

Diimide is most effective at reducing unpolarized carbon-carbon double or triple bonds. In reactions with other unsaturated systems, disproportionation of diimide to nitrogen gas and hydrazine is a competing process that significantly degrades the reducing agent.

Diimide Reduction is a stereospecific process in chemistry where alkenes or alkynes are reduced by diimide, leading to the formation and loss of a stable N2 molecule, and preferentially targeting symmetrical homonuclear double bonds over heteronuclear double bonds.

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 …

Aug 26, 2016 · We have also explored new designs, synthesis, and progress in the field of core-substituted naphthalene diimides (cNDIs), and their implications in areas such as artificial photosynthesis and solar cell technology.

There are three potential structures for diimide: cis – and trans -diimide and 1,1-diimide (aminonitrene). trans -Diimide can be generated and trapped at low temperature by a gas-phase electric discharge in hydrazine and by the thermal decomposition of metal salts of p -toluenesulfonylhydrazide.

Oct 15, 2004 · There are three potential structures for diimide: cis - and trans -diimide and 1,1-diimide (aminonitrene). trans -Diimide can be generated and trapped at low temperature by a gas-phase electric discharge in hydrazine and by the thermal decomposition of metal salts of p -toluenesulfonylhydrazide.

Diimide (HN=NH) is a useful reagent for selective reduction, as illustrated by the conversion of 15 to 17. David R. Carbery of the University of Bath devised (J. Org. Chem.2009, 74, 3186.

The compound N 2 H 2 has been called many things over the years, including diimide, diimine, dimid, diamin, diazen and diazene. The name diazene has been promoted in recent years in an attempt to systematize the nomenclature of the nitrogen hydrides, and has been adopted by Chemical Abstracts.
