There　is　an　increasing　demand　of　using　the　low-cost　and　sustainable　cobalt　to　replace　its　noble　congeners　(rhodium　and　iridium)　as　reflected　by　the　recent　upsurge　of　cobalt　catalysis　in　the　diverse　organic　transformations.　Since　all　the　redox　reactivity　of　cobalt　catalysis　highly　relies　on　the　capability　of　the　interconversion　between　their　oxidation　states　(most　frequently　+1,　+2　and　+3),　electrochemistry　perfectly　meets　such　a　requirement　owing　to　its　outstanding　performance　in　the　redox　manipulation.　In　this　review,　we　highlight　the　recent　advances　in　the　merger　of　cobalt　catalysis　and　electrochemistry　in　organic　synthesis.　(C)　2020　Chinese　Chemical　Society　and　Institute　of　Materia　Medica,　Chinese　Academy　of　Medical　Sciences.　Published　by　Elsevier　B.V.　All　rights　reserved.
