Using internal electrostatic fields to manipulate the valence manifolds of copper complexes.

ABSTRACT: A series of tetradentate tris(phosphinimine) ligands (^R3P₃tren) was developed and bound to Cu^I to form the trigonal pyramidal, C _3v-symmetric cuprous complexes [^R3P₃tren-Cu][BAr^F ₄] (1PR3) (PR₃ = PMe₃, PMe₂Ph, PMePh₂, PPh₃, PMe₂(NEt₂), BAr^F ₄ = B(C₆F₅)₄). Electrochemical studies on the Cu^I complexes were undertaken, and the permethylated analog, 1PMe3, was found to display an unprecedentedly cathodic Cu^I/Cu^II redox potential (-780 mV vs. Fc/Fc⁺ in isobutyronitrile). Elucidation of the electronic structu
