描述

應用

Malononitrile is an active methylene reagent useful for condensation reactions to synthesize various synthetic intermediates and heterocycles.[1][2][3] It is extensively used in the Knoevenagel condensation with various aldehydes and ketones.[1][4]
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.[5]
• Synthesis of polysubstituted dihydropyridines.[6]
• Synthesis of various chromene derivatives upon treating with salicylic aldehydes.[7]
• Synthesis of triselenium dicyanide by treating it with selenium dioxide.[8]
