Progress in Research on the Preparation of 2, 5-Furandicarboxylic Acid by Hydroxymethylfurfural Oxidation

Catalysts, Journal Year: 2025, Volume and Issue: 15(4), P. 373 - 373

Published: April 11, 2025

Hydroxymethylfurfural (HMF) is a substance produced in sugar-rich foods through the Maillard reaction or thermal degradation. It has been shown that when HMF content reaches certain dose, it causes harm to human health. In many food quality tests, of can be used as an important indicator. Therefore, hydroxymethylfurfural too high, will cause damage body. But conserve resources, converted into valuable chemicals, so achieve effective use resources. rich fructose and glucose easily transformed HMF. necessary study conversion pathway foods. 2, 5 furandicarboxylic acid (FDCA) obtained oxidation reaction. Due similarity its structure polymer monomer terephthalic acid, renewable substitute petroleum-based process synthesizing food-contact materials. very significant explore FDCA.

Functional group transfer strategies unlock new synthetic avenues

Chem Catalysis, Journal Year: 2024, Volume and Issue: 4(5), P. 100962 - 100962

Published: April 8, 2024

Functional group transfer strategies employing bench-stable and convenient-to-handle surrogates to replace highly toxic hazardous reagents unlock novel synthetic pathways with the prospect of green sustainable chemistry. The development such tools that extend beyond use traditional unsustainable chemicals is desirable in both academic industrial research. In this perspective, we highlight recent developments representative progress area functional respect different types modes, as transition-metal-catalyzed, free-radical, ionic, well radical-ionic transfer. Furthermore, mechanistic considerations chemistry, future opportunities, challenges, efforts, are also discussed.
