Abstract

Linear trimetallic Co^III/Co^II/Co^III cobalt complexes with bridging acyl–alkoxy ligands are electrocatalysts for the reduction of tosic acid in acetonitrile. The –OCMe₂CH₂COMe complex appears to operate homogeneously, and at a modest onset overpotential of 175 mV. A turnover frequency of ca. 80 s^-1 was observed at an overpotential of 300 mV.
