Silica bonded n-propyl-1,3,5-triazine-2,4,6-triamine as a basic catalyst for synthesis of arylmethylenemalononitrile and pyran annulated heterocyclic compounds
Journal Title: Iranian Chemical Communication - Year 2017, Vol 5, Issue 4
Abstract
In the present research, silica bonded n-propyl-1,3,5-triazine-2,4,6-triamine (SPTT) was synthesized by direct incorporation of chloropropyl groups through co-condensation of tetraethyl orthosilicate (TEOS) and 3-chloropropyl trimethoxysilane (CPTMS) and subsequent grafting the melamine onto the propyl groups via simple nucleophilic substitution reaction. The catalyst has been characterized by fourier transform infrared spectroscopy (FT-IR) and thermogravimetric analysis (TGA). The catalytic activity of catalyst was probed through synthesis of arylmethylenemalononitrile and pyran annulated heterocyclic compounds.The catalytic activity of catalyst was probed through synthesis of arylmethylenemalononitrile and pyran annulated heterocyclic compounds.The catalytic activity of catalyst was probed through synthesis of arylmethylenemalononitrile and pyran annulated heterocyclic compounds.
