Abstract
The interaction of paramagnetic copper(II) ions with glucuronic acid in aqueous solution was studied by differential line broadening analysis of carbon-13 n.m.r. spectra. Evidence is presented for pH-dependent complexation behaviour, with simple carboxylate complexation dominating below pH 4.5, and a more complicated bidentate coordination mode involving O 3 above pH 4.5.Keywords
