The redox properties of rhenium alkyl complexes R-(Re) ((Re) = (η5-C5H5)Re(NO)(PPh3)) with R = PhCH2 (1) (CH3)2CHCH2 (2), and Ph(CH3)CH (3) are studied electrochemically. Cyclic voltammetric, peak current, heterogeneous charge transfer, and chronoamperometric studies in a variety of solvents indicate that 1-3 undergo initial one-electron oxidation to cation radicals R-(Re)?+. These decompose by an EC mechanism at rates that correlate with solvent donor ability. Intermediates, possibly R-(Re/solyent)?+, are detected by cyclic voltammetry. Coulometric experiments further suggest that R-(Re)?+ can catalytically oxidize solvent via R-(Re/solvent)?+. These data contrast with an earlier report describing evidence for a two-electron oxidation of 3.
