Abstract

Organic modification of sol–gel catalytic glassy electrodes made of a thin layer of organosilica doped with nitroxyl radical TEMPO (2,2,6,6-tetramethyl-1-piperidinyloxy) crucially enhances stability in the waste-free oxidation of alcohols to carbonyls in water. Structural comparison between analogous films made of organosilica and unmodified SiO2 shows that the origin of the pronounced stable activity of the ORMOSIL film lies in high hydrophobic and also in the pronounced low degree of hydrophilicity.

    This is clearly shown by comparison of the EPR signals of TEMPO chemically entrapped in methylsilica and silica matrices, with the former spectrum resembling that of TEMPO in solution and the latter pointing to a spin molecular label severely constrained in the hydrated cages of the aminopropyl-silica matrix: A.
