A series of mixed anhydrides has been prepared and characterized.The reduction potentials and the electronic absorption spectra show an interesting systematic variation which is dependent on the steric requirements of the substituents.X-ray structural results are consistent with theoretical calculations that predict structural variations which are also dependent on the size of the substituent at the anhydride terminus.Taken together, these data show that the relative molecular orbital energies, as influenced by the relative dihedral angle of the two anhydride carbonyl groups, are responsible for the observed changes in physical properties.
