Published: April 8, 2022

The access of heterocyclic compounds via direct amination C-H bonds are vital interest because their role in pharmaceutical and natural products. combination molecular iodine electricity activates benzylic bond facilitates the process intramolecular C-N formation. Iodine works as a mediator for formation activation distance through intermediate N-I under electrochemical conditions, so can be called electrocatalyst. Under both batch & flow electrochemistry similar results were obtained cyclization product with 77 78% yields respectively. However, case annulation reaction higher yield was 99% conversion conditions using our design home-made microreactor. In transformations, well reaction, no photocatalyst used. Notably, reactions work safe environmentally friendly continuous products obtained.

Abstract: Sodium sulfinates have been widely utilized as sulfonyl radical precursors for preparing a diverse array of value-added sulfur-containing compounds (sulfones, sulfonamides, sulfonates, thiosulfonates, etc.) through S-C, S-N, S-O and S-S bonds formation reactions. Organic electrosynthesis has become an attractive alternative to conventional methods redox reactions because it utilizes electric current instead chemical agents. As such, the electrochemical generation radicals from sodium their applications in organic attracted much attention. In this review, recent advances sulfonylation involving since 2015 were reviewed, along with related reaction mechanisms.

Although C–H bond functionalization has been extensively studied since its discovery in 1955, the borylation of organic compounds by activating bonds only became popular valuable Hartwig 1995 who considered a wider application these transformations synthetic chemistry. For borylation, catalytic activation this generally low-reactivity can be performed many ways. Among approaches reported are use and stoichiometric reagents, thermal activation, photochemical suitable substrates. Iridium-, ruthenium-, rhodium-based protocols using have played crucial role toward establishment area. Photochemical though, scarcely explored despite fact that it represents comparably environmentally benign protocol light as renewable energy source. In literature survey, we highlight recent developments from initial inception up to latest advancements.

Abstract C−H bond functionalization generates molecular complexity in single‐step transformation. However, the activation of bonds requires expensive metals or stoichiometric amounts oxidizing/reducing species. In many cases, they often require pre‐functionalization starting molecules. Such pre‐activating measures cause waste generation and their separation from final product is also troublesome. such a scenario, reactions activating elements generating renewable energy resources as electricity light would be more efficient, green, cost‐effective. Further, incorporation growing flow technology chemical transformation processes will accelerate safer accesses valuable products. Arenes & heteroarenes are ubiquitous pharmaceuticals, natural products, medicinal compounds, other biologically important Herein, we discussed enabling tools technologies used for recent arenes heteroarenes.
