“…The authors explored the effect of combining N 2 at different pressures with O 2 in order to control selectivity (Scheme 14). 37 A heterogeneous system composed by iron oxide coated platinum nanowires (Pt@Fe 2 O 3 NWs) was reported by Hong et al as selective and reusable for the oxidation of styrene to benzaldehyde. However, only moderate to poor yields were obtained from monosubstituted styrene derivatives.…”

This review provides an overview of the recent developments on the oxygen-mediated cleavage of olefins and acetylene derivatives to provide carbonyl and carboxylic compounds. A number of photo, organo, and metal catalysts have been reviewed with an emphasis on those exhibiting superior performance. For this purpose, crucial aspects such as pressure, substrate scope, product selectivity for the target aldehydes, ketones, or carboxylic acids, catalyst amount, and recyclability are discussed. Although many improvements are required to match the results provided by conventional oxidants, aerobic cleavage of such unsaturated hydrocarbons is a very promising field in progress on account of the significant achievements extracted from the recent literature. Several postulated mechanisms are also provided to gain insight into the role of the catalysts and the incorporation of oxygen atoms into the products.

“…However, because oxygen molecule cannot be activated directly by NHPI in the absence of co-catalyst at room temperature, a co-catalyst is required for this catalytic reaction. Iron has a number of advantages over other transition metals for it's relatively non-toxic, cheap and environmentally friendly [27], and iron-based catalyst systems have been applied in a variety of organic transformations [28][29][30][31][32][33][34][35][36], especially in some oxidation reactions using oxygen as oxidant [37][38][39]. Therefore, we supposed iron salts have a potential as good co-catalysts in NHPI catalytic system and applied NHPI and iron salts as the catalytic system to the oxidation of alcohols.…”

“…To gain insight into their catalytic activities for lignin depolymerization, seven catalytic systems were monitored: Fe 2 (SO 4 ) 3 , Fe(NO 3 )·9H 2 O, Mn(SO 4 )·H 2 O, Bi 2 (SO 4 ) 3 , Bi(NO 3 ) 3 ·5H 2 O, H 2 WO 4 , and Na 2 WO 4 ·2H 2 O. Results concerning the use of these catalysts for oxidation catalysis − and lignin depolymerization , have been published in the literature. The reaction was performed using 2 equiv of 30% H 2 O 2 during 1 h in a mixture of acetone and water (1/1: v/v) which is able to partly dissolve the kraft lignin even at 25 °C (295 mg dissolved in 10 mL).…”

The hydrogen peroxide mediated oxidative depolymerization of kraft lignin was investigated in the presence of different metal salt catalysts in acetone/water (1/1 v/v) at low temperature. Na 2 WO 4 •2H 2 O appeared to be the best catalyst, yielding four vanillin-based monomers. Using the optimized conditions, monomers were obtained in 0.51 wt % yield from lignin. This result is among the best depolymerization yield obtained from lignin using hydrogen peroxide mediated oxidation. Optimization of the reaction conditions (temperature, catalyst loading, oxidant amount) revealed that the monomer formation is closely related to the cleavage vs recombination of the intermediates. In addition, the use of ultrasound irradiation involves higher oxidative coupling of phenoxy radicals resulting from lignin polymerization.
