“…Moharreri et al 91 utilized mesoporous MnO x as an additive-free and solvent-free catalyst for the esterification of alcohols to esters. They found that that by altering the solvent, the formation of esters/acids from the aerobic oxidation of benzyl alcohols could be manipulated.…”

“…Synthetic protocols with high atom economy are of growing need in catalysis over recent years. , Readily available manganese oxide materials have high thermal stability, and the presence of versatile crystal structures makes them attractive candidates as catalysts . Furthermore, manganese oxides can accommodate cations in the structure for balancing charge or on the surface to enhance the catalytic activity. − The introduction of alkali and alkaline earth metals by impregnation has given fruitful results to eliminate the addition of an external base to the reactions. Lattice oxygen plays the role of H abstraction by the enhanced basicity due to the introduced electropositive ions .…”

This study reports a novel methodology for the production of allyl acrylate from allyl alcohol solely as the starting substrate. The reaction reported here utilizes a heterogeneous reusable catalyst based on Li-ion-promoted mesoporous manganese oxide. The reaction conditions are mild (ambient pressure and temperature of 80 °C). The catalytic activity, selectivity, and substrate scope of the reaction are reported (60% yield). The system proposed here is composed of an allylic alcohol substrate, O2 as the oxidant, N-hydroxyphthalimide (NHPI) as the promoter, and trichloro acetonitrile (CCl3CN) as the solvent together with the Li-promoted manganese oxide (surface area >150 m2/g) as the catalyst.

Esters and ethers are widely used in modern organic synthesis. In recent years, the synthesis of esters by the dehydrogenative coupling of primary alcohols has been reported to be an environmentally benign process. In this situations, if a single catalyst can be used for the synthesis of either esters or ethers by making slight alterations to the reaction conditions, the value of the synthetic methodology would increase. In this study, we successfully developed a new catalytic function switching system: not only dehydrogenative esterification but also dehydrative etherification under environmentally friendly conditions were accomplished by the employment of a single iridium catalyst based on catalytic function switching. Using benzyl alcohol as a starting material, the esterification product, benzyl benzoate, and the etherification product, dibenzyl ether, were obtained in 92 % and 89 % yields, respectively, by employing same iridium catalyst precursor bearing a dihydroxybipyridine ligand, under optimized conditions.
