Abstract
|
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 aaryloxy alcohols as new compounds by the reaction of phenol or thiophenols with various epoxides. The structure of a-aryloxy alcohols were fully characterized by FT-IR, 1H NMR and 13C NMR as well as mass spectra.
