Abstract
Adduct formation constants, K1, for equilibria of the type, CuL2+ py ⇌ CuL2(py), where L =(MeCO·CR·COMe; R = Me, H, Cl, Ac, CO2Et, CN, and NO2) and py = pyridine, have been determined in benzene, acetone, and acetonitrile solution at 22 °C. The values of K1 are correlated with the electronic nature of the substitutent, R, and the dielectric constant of the solvent. In two cases, R = CN and NO2, further equilibria of type CuL2py + py ⇌ CuL2(py)2 have been observed at high pyridine concentrations and diadduct formation constants, K2 have been determined.
