Organic　electrosynthesis　has　been　widely　used　as　an　environmentally　conscious　alternative　to　conventional　methods　for　redox　reactions　because　it　utilizes　electric　current　as　a　traceless　redox　agent　instead　of　chemical　redox　agents.　Indirect　electrolysis　employing　a　redox　catalyst　has　received　tremendous　attention,　since　it　provides　various　advantages　compared　to　direct　electrolysis.　With　indirect　electrolysis,　overpotential　of　electron　transfer　can　be　avoided,　which　is　inherently　milder,　thus　wide　functional　group　tolerance　can　be　achieved.　Additionally,　chemoselectivity,　regioselectivity,　and　stereoselectivity　can　be　tuned　by　the　redox　catalysts　used　in　indirect　electrolysis.　Furthermore,　electrode　passivation　can　be　avoided　by　preventing　the　formation　of　polymer　films　on　the　electrode　surface.　Common　redox　catalysts　include　N-oxyl　radicals,　hypervalent　iodine　species,　halides,　amines,　benzoquinones　(such　as　DDQ　and　tetrachlorobenzoquinone),　and　transition　metals.　In　recent　years,　great　progress　has　been　made　in　the　field　of　indirect　organic　electrosynthesis　using　transition　metals　as　redox　catalysts　for　reaction　classes　including　C-H　functionalization,　radical　cyclization,　and　cross-coupling　of　aryl　halides-each　owing　to　the　diverse　reactivity　and　accessible　oxidation　states　of　transition　metals.　Although　various　reviews　of　organic　electrosynthesis　are　available,　there　is　a　lack　of　articles　that　focus　on　recent　research　progress　in　the　area　of　indirect　electrolysis　using　transition　metals,　which　is　the　impetus　for　this　review.　(c)　2021　Science　China　Press.　Published　by　Elsevier　B.V.　and　Science　China　Press.　All　rights　reserved.
