The in situ formation of ternary adducts of yttrium(III) polyaminocarboxylate complexes with the endogenous molecules pyruvate, bicarbonate or acetate are investigated using 13C NMR, SABRE-hyperpolarised NMR, and DFT. A novel [Y(EDTA)(pyruvate hydrate)(H2O)]2− adduct is linked to decomposition of pyruvate to form aceticacid and CO2 highlighting the potential of these adducts for capture and activation
使用13 C NMR、SABRE-超极化 NMR 和 DFT研究了钇 (III) 聚氨基羧酸盐络合物与内源性分子丙酮酸盐、碳酸氢盐或乙酸盐的三元加合物的原位形成。一种新型 [Y(EDTA)(丙酮酸水合物)(H 2 O)] 2−加合物与丙酮酸分解形成乙酸和 CO 2相关,突出了这些加合物捕获和激活小分子的潜力。
