A novel strategy of photocatalytic C(sp3)−H bond oxidation of various aryl ethers to esters using oxygen as the oxidant was developed. Mechanistic studies reveal the HAT process via photoredox ...

While primary alkyl esters generally react smoothly at 90 °C, the reactions of secondary and tertiary alkyl esters as well as aryl esters require higher temperatures (120–140 °C) (Figs 3 and 4).

New catalysts enable greener ester synthesis Scientists create 1 nm-sized metal-based catalysts for efficient and environmentally friendly chemical reactions Peer-Reviewed Publication ...

This leads to in situ formation of reactive aryl esters and a significant enhancement of the end group reactivity during polycondensation, the last stage of polyester synthesis when isosorbides ...
