“…Analogously, alcohols would undergo oxidation to form aldehyde intermediates on platinum and boron-doped diamond (BDD) catalysts (Figure 3c and 3d), which subsequently reacted with ammonia to yield amides. [16] The highest Faraday efficiency for the formation of amides was up to 40 %. By replacing ammonia with organic amine molecules and substituting other alcohols with ethanol, a wide range of long amides can be synthesized, e. g., acetamide, propenamide, and formyl methylamine, N, N-dimethylacetamide.…”

Tandem synthesis, the integration of multiple chemical transformations into a single process, has emerged as a promising strategy to streamline the synthesis of valuable chemicals. Meanwhile, electrocatalysis has garnered significant attention as a versatile tool for driving various chemical reactions through the application of electrical energy. This review highlights the synergistic potential of tandem synthesis and electrocatalysis, focusing on their combined applications in the efficient production of valuable chemicals. The inherent selectivity of electrocatalytic processes, coupled with the ability to manipulate reaction pathways using precise control of electrode potentials, offers a platform for designing intricate tandem reactions. Through a comprehensive survey of the literature, we showcase key examples where tandem electrocatalytic processes have enabled the conversion of simple starting materials into valuable target molecules, minimizing waste and energy consumption. We also discuss mechanistic insights that underpin these reactions and provide perspectives on the future directions and challenges in this rapidly evolving field.

“…At the same time, they exhibited an economic advantage approach to transform methanol and ammonia into formamide via Pt electrocatalyst, which can provide a FE of 40.39% at 100 mA cm −2 and operate stably for 46 h in the flow cell (Figure 13f–g). [ 85 ] It was proved that an aldehyde‐like intermediate (*CH 2 O) could combine with *NH 2 intermediate to CN coupling via feedstock replacement experiment. In situ ATR‐FTIR and online DEMS were carried out for a real‐time monitor to further understand the catalytic process.…”

The efficient conversion and utilization of CO2 is imminent due to the increase of global CO2 emissions year by year, so the strategy of electrocatalytic CO2 reduction to high value‐added chemicals comes into being. The CO2 reduction reaction (CO2RR) can yield diversified products, including C1 (like CO, CH4, etc.), C2 (like C2H4, C2H5OH, etc.), and other multicarbon compounds. Thereinto, selective transformation to C2 compounds is relatively significative by reason of high industrial value but being greatly challenging, particularly involving complex CC coupling. Herein, the reaction mechanisms of several C2 products (including C2H4, C2H5OH, and H2C2O4) and corresponding latest research progress are summarized and discussed. Besides, N atoms, from N2, nitrates, and nitrites, are integrated into CO2RR to yield nitrogen‐containing organics (like urea, amides, and amines), broadening the application field of CO2RR. Therefore, the part on the electrocatalytic coupling of CO2 and nitrogen sources (including N2, NO3−, NO2−) by CN bonds is also delved in this review, including recent advances, reaction mechanisms, and related key intermediates.

“…Methanol can be massively produced from CO 2 and biomass conversion [10] . Updating sustainable methanol to high‐valued chemicals can reduce the current dependence on fossil energy [11,12c] . Thus, it is highly desirable to achieve the scalable electrosynthesis of formamide from soluble methanol and ammonia with a large Faradaic efficiency at an industrial current density using a large and durable electrode, especially driven by renewable energy.…”

The scalable and durable electrosynthesis of high-valued organonitrogen compounds from carbonand nitrogen-containing small molecules, especially operating at a high current density, is highly desirable. Here, a one-pot electrooxidation method to synthesize formamide (HCONH 2 ) from methanol and ammonia over a commercial boron-doped diamond (BDD) catalyst is reported. The formamide selectivity from methanol and formamide Faradaic efficiency (FE HCONH 2 ) achieve 73.2 % and 41.2 % at the current density of 120 mA cm À 2 with high durability. The CÀ N bond originates from the nucleophilic attack of ammonia on an aldehyde-like intermediate. Impressively, an 8 L electrolyzer is employed for the pilot plant test over a 2200 cm 2 BDD electrode, which exhibits 33.5 % FE HCONH 2 at 120 mA cm À 2 (current: 264 A) with a yield rate of 36.9 g h À 1 , demonstrating the potential of this technique for large-scale electrosynthesis of formamide.
