Abstract
In the previous publication, some of us reported the conversion of a copper(I) complex to a copper(II) oxalate complex, and claimed that this conversion involved a reduction of CO 2 to oxalate (C 2 O 4 2− ). Herein, we show that the oxalate is produced not by reduction of CO 2 , but by reaction of ascorbate with oxygen. We also present new results that explain in a more comprehensive way the behaviour of these copper compounds under O 2 and CO 2 .
