The electrooxidation of alcohols in an aqueous disperse system with N-oxyl-immobilized poly( p-phenylene benzobisthiazole) network polymer particles ( PBZT NT-N-Oxyl ) as a disperse phase was performed successfully in a simple beaker-type undivided cell under a constant current condition to afford the corresponding ketones, aldehydes, and/or carboxylic acid in moderate to good yields. Recycle use of both the PBZT NT-N-Oxyl particles and the aqueous media could be achieved successfully by immobilization of additional N-oxyl moiety on the polymer particles in an appropriate interval. Notably, the shape and the particle size of PBZT NT-N-Oxyl were not appreciably changed even after 60 times recycle use. [Display omitted]
