In this work, graphitic carbon nitride (g-C3N4) decorated with molybdenum-substituted tungstophosphoric acid as a novel photocatalyst (H3PW4Mo8O40/g-C3N4) was used to catalyze the oxidation of alcohols and sulfides. H3PW4Mo8O40/g-C3N4 (PW4Mo8/g-C3N4) displays higher photocatalytic activity under visible light irradiation for the oxidation of alcohols and sulfides compared with Keggin/g-C3N4 (PW12/g-C3N4). To obtain the optimum value, molybdenum substitution contents (H3PW12-xMoxO40) were changed from x = 4 to 12. The results showed that PW4Mo8 produces the best yield under visible-light irradiation. The results showed that PW4Mo8 was the best sample. The reaction rate increase can be due to the redox and acid properties of PW4Mo8/g-C3N4. This study provides a new insight for the preparation of highly efficient photocatalysts for the oxidation of organic compounds.

An efficient selective oxidation of sulfides to sulfoxides has been developed by means of AlCl 3 -promoted oxygen transfer from phenyliodine diacetate [PhI(OAc) 2 ]. AlCl 3 proved to be the optimalLewis acid for the activation of PhI(OAc) 2. Various substituted sulfides were selectively transformed into the corresponding sulfoxides in good to excellent yields (≤99%). The high efficiency, excellent functional-group compatibility, broad substrate scope, and mild conditions render the current transformation useful for the synthesis of sulfoxides.

The oxidation of organic sulfides by imidazolium fluorochromate resulted in the formation of the corresponding sulfoxides. The reaction is first order with respect to imidazolium fluorochromate. A Michaelis-Menten type kinetics was observed with respect t
