Preparation and identification of salen-Cu stabilized on the periodic mesoporous organosilica and its application as effective catalyst in the synthesis of hexahydroquinolin derivatives

In this study, we first developed the copper salon complex according to pre-synthesized methods, and after that, periodic mesoporous organosilicas was prepared and used as a heterogeneous substrate for the stabilization of the copper salon complex. and by various analyzes such as Fourier transform infrared spectroscopy (FTIR), thermal gravimetric analysis (TGA) and scanning electron microscopy (SEM) was identified and then, to study the catalytic activity in a one-pot and multi-component reaction, thepreparation of hexahydroquinolin derivatives was investigated. as well as catalyst reuse was investigated. We observed that the catalyst was used in the 5 reaction cycles without significantly reducing catalytic activity.
