- 中文摘要: The complexation kinetics of the reaction of copper(II) with isomeric tetraamine macrocyclic ligands, C-rac-5,7,7,12,12,14-hexamethyl-1,4,8,11- tetraazacyclotetradecane (tet c), C-meso-5,7,7,12,12,14-hexamethyl-1,4,8,11- tetraazacyclotetradecane (tet d), and C-meso-5,5,7,12,12,14-hexamethyl-1,4,8,11- tetraazacyclotetradecane (tet a) in strongly basic aqueous media have been examined at 25.0.plmin.0.1.degree.C by means of the stopped-flow technique. The variation in the values of the resulting rate constants indicates that the positions of the methyl substituents play a significant role in these reactions. These reactions exhibit associative character and second-bond formation is proposed as the rate-determining step.
