Effects of Charged Ligand Substituents on the Properties of the Formally Copper(III)-Hydroxide ([CuOH]²⁺) Unit.

ABSTRACT: With the goal of understanding how distal charge influences the properties and hydrogen atom transfer (HAT) reactivity of the [CuOH]²⁺ core proposed to be important in oxidation catalysis, the complexes [M]₃[^SO3LCuOH] (M = [K(18-crown-6)]⁺ or [K(crypt-222)]⁺) and [^NMe3LCuOH]X (X = BAr^F₄^- or ClO₄^-) were prepared, in which SO₃^- or NMe₃⁺ substituents occupy the para positions of the flanking aryl rings of the supporting bis(carboxamide)pyridine ligands. Structural and spectroscopic characterization showed that the [CuOH]⁺ cores in the corresponding complexes were similar, but cyclic voltammetry revealed the E_1/2
