  Tetrafluoroboric acid (HBF4) and triethylamine (Et3N) have been added consecutively to solutions of tetranuclear oxocopper(II) complexes (mu-4-O)py3Cu4Cl4O (18), (mu-4-O)py4Cu4Cl4O (Ib), (mu-4-O)py4Cu4Cl6 (IIa), (mu-O)2N4Cu4Cl4 (IIIa) and (mu-4-O)N4Cu4Cl6 (IVa) in nitrobenzene at 25-degrees-C to examine their proton basicities. Here, py is pyridine and N is NN-diethylnicotinamide. The reactions were assigned from spectral and conductivity data. We conclude that the mu-4-oxo groups of IIa and IVa are reversibly monoprotonated by HBF4 and are less basic than Et3N. Further addition of HBF4 apparently removes the central mu-4-oxo group of Ila and IVa as H3O+ and then protonates coordinated py and N. Complexes Ia, Ib and IIIa are irreversibly monoprotonated at their respective oxo groups, which are more basic than Et3N. The protonation sequence for Ia consists of loss of its terminal oxo group Cu(v)-O as H3O+, followed by loss of coordinated py as pyH+. The sequence for Ib is the same except that py coordinated at the v site of lb is protonated in preference to py at sites x. The mu-4-oxo group of Ia and Ib and the OH groups of diprotonated Ma are less basic than their respective ligands py and N. Implications of the results on the mechanisms of copper-catalyzed phenolic oxidative coupling reactions are considered.
