3-氨基丁烯腈

3-Aminocrotononitrile reacts with ferrocenyl-1,2-enones to form ferrocenyl pyridines. It undergoes diazotization coupling reaction with p-substituted anilines to give 2-arylhydrazone-3-ketimino-butyronitriles.3-Aminocrotononitrile, (E)+(Z), is used in reaction with aryldiazonium salts gave, instead of the expected triazene, 2-arylhydrazono-3-ketobutyronitrile by electrophilic attack at the ?-carbon and hydrolysis of the resulting imine. It is also used as an important raw material and intermediate used in organic Synthesis, pharmaceuticals, agrochemicals and dyestuff. 3-Aminocrotononitrile was used as bisnucleophilic reagent which on cyclocondensation with hexafluoroacetone(ethoxycarbonylimine) forms bis(trifluoromethyl)pyrimidinones.
