Popis:	A simple and convenient methodology for the synthesis of various substituted benzylidene malononitrile derivatives using amino acid functionalized silica as heterogeneous catalyst, since amino acids recently emerged as a class of broadly useful organocatalysts for carbon–carbon bond formation reactions. This method has several advantages including good isolated yields of the products and easy workup. Moreover, the catalyst also showed good activity and could be recovered and recycled with much loss of activity rendering the process more economic and fall in the domain of green chemistry.
