Anion- and Water-facilitated Oxidative Carbon-Carbon Bond Cleavage and Diketonate Carboxylation in Cu(II) Chlorodiketonate Complexes.

ABSTRACT: The O₂-dependent carbon-carbon (C-C) bond cleavage reactions of the mononuclear Cu(II) chlorodiketonate complexes [(6-Ph₂TPA)Cu(PhC(O)CClC(O)Ph)]ClO₄ (1-ClO ₄ ) and [(bpy)Cu(PhC(O)CClC(O)Ph)(ClO₄)] (3-ClO ₄ ) have been further examined in terms of their anion and water dependence. The bpy-ligated Cu(II) chlorodiketonate complex 3-ClO ₄ is inherently more reactive with O₂ than the 6-Ph₂TPA-ligated analog 1-ClO ₄ . Added chloride is needed to facilitate O₂ reactivity for 1-ClO ₄ but not for 3-ClO ₄ at 25(1) °C. Evaluation of k _obs for the reaction of
