Synthesis of Aminophenylpolycarbonitriles from Arylidenemalononitriles by the Michael Reaction
摘要:
The reactions of arylidenemalononitriles with malononitrile, methyl cyanoacetate and cyanoacetamide yielded aminophenyldi- and tricarbonitriles. Formation of these compounds occurs through the dehydrocyanation step of the corresponding aminohexenepolycarbonitriles.
