This paper presents the solar-driven electrocarboxylation of 2-bromopyridine (2-BP) with CO2 into high-value-added chemicals 2-picolinic acid (2-PA) using dye-sensitized photovoltaics under simulated sunlight. Using three series-connected photovoltaic modules and an Ag electrode excellent catalytic performance, a Faraday efficiency (FE) 33.3% is obtained for 2-PA mild conditions. The experimental results show that photovoltaics-driven systems conversion heterocyclic halide to afford value-added carboxylic are feasible effective.

ConspectusElectrochemistry has been used as a tool to drive chemical reactions for more than two centuries. With the help of an electrode and power source, chemists are provided with system whose potential can be precisely dialed in. The theoretically infinite redox range renders electrochemistry capable oxidizing or reducing some most tenacious compounds. Indeed, electroreduction offers alternative generating highly active intermediates from electrophiles (e.g., halides, alkenes, etc.) in organic synthesis, which untouchable traditional reduction methods. Meanwhile, reductive coupling extensively utilized both industrial academic settings due their ability swiftly, accurately, effectively construct C–C C–X bonds, present innovative approaches synthesizing complex molecules. Nonetheless, its application is constrained by several inherent limitations: (a) requirement stoichiometric quantities agents, (b) scarce activation strategies inert substrates high potentials, (c) incomplete mechanistic elucidation, (d) challenges isolation intermediates. merging represents attractive approach address above limitations synthesis seen increasing use synthetic community over past few years.Since 2020, our group dedicated developing electroreductive cross-coupling using readily available small molecules, such arenes, CO2, D2O, value-added products. Electroreductive chemistry versatile powerful capacity precise selectivity control, allowed us develop three electrochemical modes lab: (1) An economically advantageous direct (EDR) strategy that emphasizes efficiency, achieves atom utilization, minimizes unnecessary atomic waste. (2) A class organo-mediated (EOMR) methods controlling reaction pathways. This allows modulation processes enhance efficiency selectivity. (3) metal-catalyzed (EMCR) method enables selective functionalization specific bonds functional groups under mild conditions, thereby occurrence side reactions. We commenced studies establishing organic-mediator-promoted carboxylation aryl alkyl halides. was then employed arylcarboxylation simple styrenes halides manner. electrolysis arenes epoxides CO2 carboxyl source achieved. Moreover, through adjustment we successfully accomplished deuteration olefins, unactivated enabling efficient formation D-labeled Finally, building on previous understanding developed series alkylation enable C(sp3)–C(sp3)
