A practical RuCl3-catalyzed oxidation using trichloroisocyanuric acid (TCCA)

The combined use of catalytic RuCl3 (1.0 mol %) and stoichiometric trichloroisocyanuric acid (TCCA) in the presence of n-Bu4NBr (2.0 mol %) and K2CO3 (3.0 equiv) in 1:1 MeCN/H2O at 25?45 °C allows smooth oxidation of primary alcohols to carboxylic acids. Secondary alcohols can be oxidized to ketones when using the same set of the reagents in 1:1 MeCN/H2O or 1:1 AcOEt/H2O. By proceeding under the nonacidic biphasic conditions dispensing with hazardous reagents, the oxidation reactions are applicable to structurally diverse alcohols, easy to work up, environmentally benign, and basically high-yielding.
Trichloroisocyanuric acid (TCCA):
 Be more widely applied in its sterilization effect, stability, harmless and easy to use: 
① can effectively kill a variety of fast bacteria, fungi, spores, mold, Vibrio cholerae. To kill hepatitis A, hepatitis B virus effects of the HIV virus and also has a good disinfection. 
② chlorine content of up to 90%, and very stable, its chlorine content to store a year fell less than 1%.
③ harmless, odor, and easy to use, trichloroisocyanuric acid (TCCA) disinfection tablets can just be thrown into the pool can be quickly dissolved achieve sterilization effect.
 So for swimming pool disinfection, the trichloroisocyanuric acid (TCCA) better, its many advantages is its reason replace sodium hypochlorite.
