Electron-Transfer Kinetics of Copper(II/I) Complexes with Dialcoholic Derivatives of the Macrocyclic Tetrathiaether [14]aneS4. Effect of Simple Ring Substituents upon Gated Behavior

Studies have been conducted on the electron-transfer kinetics of the Cu(II/I) complexes formed with two dialcoholic derivatives of the macrocyclic tetrathiaether [14] aneS 4 , syn- and anti-3,6,10,13-tetrathiacyclotetradecane-1,8-diol. For Cu II / I (syn-[14]aneS 4 -diol), the self-exchange rate constant has been determined directly from NMR line broadening. For both Cu II / I L systems, extensive cross-reaction electron-transfer kinetics have also been measured using four different reductants and four different oxidants, spanning a wide range of reaction potentials
