Task Specific Ionic Liquid

A novel catalytic system was prepared by impregnating ionic liquid immobilized 2,2,6,6-tetramethylpiperidyl-1-oxyl (TEMPO) and copper salt onto various silica supports. This catalytic system was capable of rapidly converting different benzylic and allylic alcohols into the corresponding aldehydes under O2 atmosphere with high conversion. Recycling results showed that the catalyst could be easily recovered and reused.

AbstractWe describe the synthesis of an ionic-liquid (IL)-supported organotelluride catalyst and its application as a recyclable catalyst for the aerobic oxidation of phosphite esters to phosphate esters. This method shows high conversion rates, allows the ready isolation and purification of the resulting products, and exhibits good reusability of the catalyst.
