Abstract

Abstract The title reaction is studied with a series of CN- or COOCH3-substituted dipolarophiles. All the reactions obey the second-order rate law. The activation enthalpies and entropies are 44–52 kJ mol−1 and −(129–166) J K−1 mol−1, respectively. The rate constants are insensitive to solvent. The reactivity and product of dimethyl maleate are anomalous.
