Several other methods exist for the synthesis of imines.
* Reaction of organic azides with metal carbenoids (produced from diazocarbonyl compounds).
* Condensation of carbon acids with nitroso compounds.
* The rearrangement of trityl N-haloamines in the Stieglitz rearrangement.
* By reaction of alkenes with hydrazoic acid in the Schmidt reaction.
* By reaction of a nitrile, hydrochloric acid, and an arene in the Hoesch reaction.
* Multicomponent synthesis of 3-thiazolines in the Asinger reaction.
* Thermal decomposition of oximes.
