Nano-SiO₂/DBN: an efficacious and reusable catalyst for one-pot synthesis of tetrahydrobenzo[b]pyran derivatives.

ABSTRACT:

Background

The nano-sized particles enhance the exposed surface area of the active part of the catalyst, thereby increasing the contact between precursors and catalyst considerably. In this study, nano-SiO₂/1,5-diazabicyclo[4.3.0]non-5-en was synthesized, characterized and used as a heterogeneous nanocatalyst for the synthesis of tetrahydrobenzo[b]pyran derivatives. Fourier Transform Infrared Spectroscopy, Field Emission Scanning Electron Microscopy, Brunauer-Emmett-Teller plot, Energy Dispersive X-ray Spectroscopy and Thermo Gravimetric Analysis were used to discern nano-SiO₂/1,5-diazabicyclo[4.3.0]non-5-en.

Results

Tetrahydrobenzo[b]pyrans were synthesized by using nano-SiO₂/1,5-diazabicyclo[4.3.0]non-5-en via one-pot three-component conden
