Copper(II) acetate reacts with pyridine and quinoline bases in dioxane giving rise to adduct compounds, which were characterized by UV and EPR techniques. The reaction is formulated as follows:<BR>Cu<SUB>2</SUB>(OAc)<SUB>4</SUB>+L\overset<I>K</I><SUB>21</SUB>\rightleftharpoonsCu<SUB>2</SUB>(OAc)<SUB>4</SUB>L,<BR>where L denotes a free base and <I>K</I><SUB>21</SUB> is an adduct formation constant. Values of <I>K</I><SUB>21</SUB> range from 12 for quinoline or 2-picoline to 146 mol<SUP>−1</SUP> dm<SUP>−3</SUP> for 4-ethylpyridine. A linear free energy relationship is observed between the adduct formation and the protonation of bases in water except for sterically crowded bases.
