Abstract

Oxidation of alkynes, both terminal and internal, is performed by hydrogen peroxide in the presence of catalytic amounts of (cetylpyridinium) 3PM1204 (M= Mo (VI), W (VI)). A comparison with the analogous oxidation reactions catalyzed by Na2MO4 reveals that PM120403-anions are more efficient catalysts than M042-in the oxidation of terminal alkynes to carboxylic acids. The higher catalytic activity of peroxometalates allows the ...
