Glycolic acid (GA), as important building block of biodegradable polymers, has been synthesized for the first time in excellent yields at room temperature by selective oxidation of 1,3-dihyroxyacetone (DHA) using a cheap supported Cu/Al2O3 catalyst with single active Cu-II specks. By combining EPR spin-trapping and operand degrees ATR-IR experiments; different mechanisms for the co-synthesis of GA, fornzates, and formamides have been derived, in which (OH)-O-center dot radicals formed from H2O2 by a Fenton-like reaction play a key role.
