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.

Oxidative potential of trans‐3,5‐dihydroperoxy‐3,5‐dimethyl‐1,2‐dioxolane (DHPODMDO) has been explored in the facile thiocyanation of anilines and indoles through the efficient and in situ generation of SCN+ ion from sodium thiocyanate.

Preyssler-type heteropolyacid supported on TiO2 nanoparticles has been explored as an efficient catalyst in selective oxidation of primary aromatic amines to azoxy derivatives using trans-3,5-dihydroperoxy-3,5-dimethyl-1,2-dioxolane as oxidant. The reactions proceeded smoothly under mild and green ultrasound-accelerated conditions to afford the products in high yields. The catalyst recovered from the reaction mixture exhibits long-term stability with no significant drop in its catalytic activity. .

The oxidative cleavage of C=C bonds adjacent to aryl and alkyl moieties was efficiently achieved with monoacetylated bishydroperoxides. The main active oxidant used in this reaction was singlet molecular oxygen, which was generated in situ from the base-mediated fragmentation of monoacetylated bishydroper­oxides. All the reactions proceeded smoothly at room temperature to furnish the respective carbonyl compounds in good yields within short reaction times.

A simple and efficient method for the selective oxidation of alcohols to ketones using trans-3,5-dihydroperoxy-3,5-dimethyl-1,2-dioxolane at room temperature is developed. The reactions were smoothly proceeded under catalyst-free conditions to provide ketones in quantitative yields within short reaction times. Also, this method is compatible with many functional groups including aldehydes, olefins, halogens, amines and esters.

Selective and efficient bromination and iodination of aromatic compounds by ammonium bromide and ammonium iodide, respectively, under promotion of trans-3,5-dihydroperoxy-3,5-dimethyl-1,2-dioxolane have been explored. Mild reaction conditions, high selectivity and yield, and high reaction rate are some of the major advantages of this synthetic method.

Catalytic potential of ammonium hypobromite in the one-pot synthesis of 3,4-dihydropyrimidin-2(1H)-ones from Biginelli-type condensation reaction between an aldehyde, β-keto ester and urea has been explored. The reaction proceeds under solvent-free conventional heating as well as microwave-irradiation conditions to afford the respective products in excellent yields.

Silica sulfuric acid (SSA) was found to efficiently catalyze the conversion of aldehydes and ketones directly into the corresponding gem-dihydroperoxides (DHPs) on treatment with aqueous 30% H2O2 at room temperature. Mild reaction conditions, good to excellent yields, short reaction times, low environmental impact, and recyclability of the catalyst are the main advantages of this synthetic method.
