Synthesis, characterization and catalytic activity of novel large network polystyrene-immobilized organic bases?
RSC Advances Pub Date: 2015-12-07 DOI: 10.1039/C5RA21140A
Abstract
In view of searching for efficient polymeric supports for organic bases to be used in environmentally friendly reaction conditions, novel gel-type cross-linked polystyrenes functionalized with diethylamine and 1,5,7-triazabicyclo[4.4.0]dec-5-ene, have been prepared. The structural properties and morphology of these catalysts have been determined by extensive solid state NMR experiments, FTIR spectroscopy and SEM/TEM microscopy. SPACeR-supported bases were found to exhibit high catalytic activity in the epoxide ring opening by phenols. A range of β-substituted alcohols have been readily and regioselectively synthesized.
