| Abstract: A catalytic reaction of cucurbit[n, n=5～8]uril have been investigated by dint of oxidative catalysts of ascorbic acid. The evidences of kinetics claimed that cucurbiturils, as catalyst accelerator, could increase oxidation rate of ascorbic acid in presence of transition metal cations, and the results of electromotive forces revealed that cucurbiturils could improve oxidative ability of Cu(Ⅱ) and Zn(Ⅱ) in different degree. | |
