Reduction of (pddi)Cr reveals redox noninnocence via C-C bond formation amidst competing electrophilicity: (cpta)CrMen- (n = 0, 1) and (pta)Cr

Reversible cyclopropane formation is probed as a means of redox noninnocence in diimine/diamide chelates via reduction and complex anion formation. Competition from imine attack renders complications in the latter approach, and electrochemical measurements with calculational support provide the rationale.Reversible cyclopropane formation is probed as a means of redox noninnocence in diimine/diamide chelates via reduction and complex anion formation.
