Synthesis of Cyclopentadiemnyk-ene-1,2-dithiolatocobalt Complexes and Coupled Proton-Electron Transfer in a Substituted Quinaxalinyl Derivatives

Abstract

A series of cyclopentadienyl-ene-1,2-dithiolatocobaIt complexes, [(η 5 -C 5 H 5 )Co(S 2 C 2 RH)], has been prepared. The derivative in which quinoxalin-2-yl is bound to the dithiolene manifests novel electrochemical behaviour in acidic media which is consistent with a coupling of metal-centered electron addition to protonation of a pyrazine ring nitrogen
