Regioselective synthesis of novel α-ariloxy alcohols over silica-bonded 1,4-diaza-bicyclo[2.2.2]octane-acetic acid bromide as new catalyst

Add time:07/25/2019    Source:sciencedirect.com

Silica-bonded 1,4-diaza-bicyclo[2.2.2]octane-acetic acid bromide (SBDBAAB) as a novel nanostructured catalyst was prepared and fully characterized by several techniques including fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermal gravimetric analysis (TGA), differential thermal gravimetric (DTG), scanning electron microscope (SEM), transmission electron microscopy (TEM), energy dispersive X-ray analysis (EDX), Brunauer-Emmett-Teller (BET) surface area analysis and Barrett-Joyner-Halenda (BJH) pore size and volume analysis. SBDBAAB was successfully tested on the synthesis of α-aryloxy alcohols as new compounds by the reaction of phenol or thiophenols with various epoxides. The structure of α-aryloxy alcohols were fully characterized by FT-IR, 1H NMR and 13C NMR as well as mass spectra.
