A kinetic investigation of the Ru-catalyzed oxidation of 1-phenyl ethanol to acetophenone using H2O2 under PT conditions shows that this system differs from classic extraction and interfacial mechanisms often encountered in PTC oxidations. Vesicles formed by the phase transfer agent in the organic phase are proposed as the catalytic reaction sites. Such structures are evidenced by microscopic studies. The effects of substituents, different phase transfer agents, and metal catalysts are studied and discussed in view of this mechanism.
