詳細

アプリケーション

Malononitrile is an active methylene reagent useful for condensation reactions to synthesize various synthetic intermediates and heterocycles. It is extensively used in the Knoevenagel condensation with various aldehydes and ketones.
Some of the reactions where malononitrile is used as a reactant are:

• Synthesis of 2-pyran-4-ylidene-malononitrile (PM) based red light emitting polymers.
• Synthesis of polysubstituted dihydropyridines.
• Synthesis of various chromene derivatives upon treating with salicylic aldehydes.
• Synthesis of triselenium dicyanide by treating it with selenium dioxide.
