our knowledge, this is one of the highest current efficiencies in
electrochemical synthesis to date in that one electron can run
the radical cation chain process up to 80 times. Taking advan-
tage of this effective radical cation chain process, we also
demonstrated that over 4 grams of the Diels–Alder adduct were
obtained with high current efficiency. The reaction was moni-
tored by GC–MS to show sigmoidal curves, suggesting the
involvement of intermediate(s) in the rate determining step. Our
findings described herein would lead to further design of SET-
triggered radical ion-based reactions involving chain processes
with high catalytic efficiency and productivity.
