The copper-TEMPO-catalysed aerobic oxidation of primary alcohols based on the new supported ionic liquid phase (SILP) catalysts is presented. CuCl₂ acts as a homogenous catalyst dissolved in the small quantity of ionic liquid dispersed in the form of film on the solid support. A bi-modal pore structure silica with a highly developed surface and an ionogel were used as solid supports. 1-Butyl-3-methylimidazolium octylsulfate as the most active “catalyst-philic” phase was found. The application of SILP catalysts for the oxidation of alcohols allows the high yields of corresponding aldehydes (92–95 % ). The catalysts were used in seven cycles without significant loss of activity. High recoveries of the catalysts were observed.
