The direct esterification of aldehydes and alcohols was carried out with pyridinium hydrobromide perbromide in water at room temperature. A variety of aldehydes were converted to respective ester derivatives with alcoholssuch as methanol, 1,2-ethanediol, 1,3-propanediol. Further, a variety of aliphatic alcohols were also converted to the corresponding Tishchenko-like dimeric esters in good yields under
Non-plasmonic metal nanoparticles as visible light photocatalysts for the selective oxidation of aliphatic alcohols with molecular oxygen at near ambient conditions
Nanoparticles (NPs) of Pd and Pt were used for the selective oxidation of aliphaticalcohols to corresponding aldehydes or esters with molecular oxygen as oxidant at near ambient temperatures under...

homogeneous Lewis acid catalyst, scandiumtriflate, into the nanocavities of a Zr MOF, MOF-808, the compound catalyst, Sc–Ru⊂MOF-808, can achieve aliphatic alcohol conversion up to 92% with ester selectivity up to 91%. A mechanistic study reveals a unique “via acetal” pathway in which the alcohol is first oxidized on Ru NPs and rapidly converted to an acetal on Sc(III) sites. Then, the acetal slowly
