The next hurdle to be addressed was identifying equipment capable of providing alternating polarity current. The expected current flow for a 1 kg reaction would be in excess of 100 A; however, no power source capable of supplying this amperage with polarity alternation was readily available on the market. Therefore, a lab potentiostat capable of a 20 A maximum output was used as a compromise. The elevated capacitance of the graphite electrode material presented an additional challenge, which was addressed by designing a custom step-down reversal of polarity (see SI for further details). Despite the equipment limitation resulting in a longer reaction time (90 hours), the kg-scale reaction proceeded smoothly, providing a comparable 80% isolated yield of olefin 1 (Figure , bottom right). To place these results in context, a hypothetical cost comparison of the analogous photochemical variant 20 is put forth, wherein the electrochemical reaction would require $89 for all the reagents to provide 675 g of 1 ($26/mol of 1), while the Ir catalyst alone would cost >$1,000 ($302/mol of 1) on the same reaction scale. Alternating polarity (AP) every 5 seconds and DC electrolysis usually share similar reactivity profiles; 30 therefore, it is of great surprise that merely switching from AP to DC results in little conversion under otherwise identical conditions (Table , entry 7). Accordingly, preliminary mechanistic investigations were conducted to provide a deeper understanding on the effect of AP on this transformation (Figure ). The most notable visual difference between the reactions with and without AP was the appearance of electrodes after completion of the electrolysis (Figure ).
