A green method for the oxidation of alcohols to carboxylic acids was developed using a novel co-catalytic system based on gold, silver, and copper catalysts. This reaction system was conducted under atmospheric oxygen in water and mild conditions to selectively oxidize 5-hydroxymethylfurfural to 2,5-furandicarboxylic acid, as a building block for polyethylene furanoate, which is a 100% bio-based, future alternative to the petroleum-based polyethylene terephthalate. Furthermore, various primary alcohols were conveniently oxidized to their corresponding carboxylic acids in up to quantitative yields.
利用基于金、银和铜催化剂的新型共催化体系，开发了一种将醇氧化为羧酸的绿色方法。该反应体系在常压氧气和水的温和条件下进行，可将5-羟甲基糠醛选择性氧化为2,5-呋喃二甲酸，后者是聚呋喃二甲酸乙二酯的一种构建单元，聚呋喃二甲酸乙二酯是100%生物基的，是石油基聚对苯二甲酸乙二酯未来的替代品。此外，各种伯醇可方便地氧化为相应的羧酸，产率高达定量。
