Acetone azine
Acetone azine is the simplest ketazine. It is an intermediate in some hydrazine manufacturing processes.Synthesis
Acetone azine can be prepared from acetone and hydrazine:
It can also be produced from acetone, ammonia and hydrogen peroxide. The first step is the formation of acetone imine, Me2C=NH; this is then oxidized by hydrogen peroxide through a complex mechanism to give 3,3-dimethyloxaziridine, which reacts with a further molecule of ammonia to produce acetone hydrazone. The hydrazone then condenses with a further molecule of acetone to produce the azine. The acetone azine product is distilled out of the reaction mixture as its azeotrope with water /n.Reactions
Acetone azine can be used to prepare acetone hydrazone and 2-diazopropane.
Hydrazine can be produced through acid-catalysed hydrolysis of acetone azine:
