Transition metal ascorbic acid reaction mechanism Three detailed mechanisms have been proposed to describe the oxidation process of ascorbic acid by iron and copper28,29,30,31. All of them begin with the oxidized form (Fe(III) or Cu(II)), consume oxygen, and produce A.−or DHA plus a ...
Release of strain and subsequent ring opening produces but - 3 - ene - 1,2 - diones which acetalise to give the ultimate reaction products 2 (or 3). With copper as catalyst byproducts were isolated, viz 1,1 - dialkoxy - 4 - hydroxy - butane - 2 - ones (4 and 5), and ...
