Abstract

The stability constants of the copper(I) π-complexes with the different acidic forms of fumaric and maleic acids (H₂L, HL^- and L^2-) were derived as (0.23, 1.2 and 2.8)×10⁴ M^-1 (maleic acid) and (0.73, 1.1 and 1.5)×10⁴ M^-1 (fumaric acid), respectively, by either electrochemical or pulse radiolytic techniques. The influence of electron-donating/withdrawing substituents on the π-ligands are discussed.
