Afzal Zafarpour Chemistry Department, Omidiyeh Branch of Islamic Azad University, Omidiyeh, Iran Behrooz Tayebi Chemistry Department, Omidiyeh Branch of Islamic Azad University, Omidiyeh, Iran Journal Article 2016 02 08 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. https://icc.journals.pnu.ac.ir/article_3195_ace03c7e8c03f0e794946ccf76c8ca1c.pdf
