SiliCycle®, has a new catalyst line of innovative products called the SiliaCat™. This new line is composed of various silica-based catalysts like the SiliaCat™ TEMPO that can easily be used to replace their homogenous equivalent in a wide variety of well-known organic reactions. These silica-based catalysts present a number of advantages over their solution phase equivalents, like the ease to remove the spent catalyst by a simple filtration. In this poster we will present different applications using the SiliaCat™ TEMPO for demonstrating the effectiveness and the versatility of this silica-based catalyst. This product will be commercially available in either in bulk, in SPE cartridges, and in Flash cartridges formats. We will investigate more applications using the SiliaCat™ TEMPO as an oxidizing catalyst to demonstrate its greater selectivity compared to the homogenous phase TEMPO during various oxidation reactions like: oxidation of alcohols (Montanari-Anelli oxidation of 1-nonanol), oxidation of vic diols to a-hydroxy acids, oxidation of amino diols, etc. We will also look at the catalytic activity efficiency and the stability of the SiliaCat™ TEMPO in several consecutive runs for some oxidation reactions. |
