Electrochemical-induced hydrofunctionalizations of alkenes and alkynes

Chemical Synthesis, Journal Year: 2024, Volume and Issue: 4(1)

Published: March 1, 2024

The hydrofunctionalizations of readily available alkenes and alkynes are one the most effective useful routes to afford diverse value-added compounds. Although traditional hydrofunctionalization strategies catalyzed by metal catalysts present convenient approaches, they also accompanied resource consumption environmental crisis. Electrosynthesis, as a renewable sustainable technology, has become cost- atom-efficient synthetic route. In this review, electrochemical-induced summarized presented. each section, electrochemical strategy access hydrogenation other (hydroboration, hydrosilylation, hydroalkylation, hydroalkoxylation, hydrocyanation, hydrocarboxylation, etc. ) products elaborated in detail separately. Finally, current challenges prospects for unsaturated carbon‒carbon (C‒C) bonds discussed briefly.

Electrochemical Annulation of ortho‐Alkynylbiphenyls to Fused Sulfenyl Phenanthrenes and Spiro Cyclohexenone Indenes

Advanced Synthesis & Catalysis, Journal Year: 2023, Volume and Issue: 366(1), P. 18 - 23

Published: Nov. 21, 2023

Abstract Here, we present an electrochemically induced synthesis of 9‐sulfenylarylphenanthrenes and 3’‐sulfenylarylspiro‐cyclohexa[4.5]trienones starting from o ‐alkynylbiphenyls diaryl disulfides. This method was accomplished through constant current electrolysis 10 mA in undivided cell setup by utilizing CH 3 CN as a solvent LiClO 4 electrolyte at room temperature. Notably, the strategy enabled formation sulfenylphenanthrenes sulfenyl spiro cyclohexa[4.5]trienones 70%–95% yield. Scale‐up synthesis, mechanistic studies, cyclic voltammetry have also been carried out.

Pd-Catalyzed Hydroboration of Vinylarenes with B₂pin₂

The Journal of Organic Chemistry, Journal Year: 2024, Volume and Issue: 89(12), P. 9056 - 9062

Published: June 10, 2024

A palladium(II)-catalyzed Markovnikov hydroboration of aryl alkenes with readily available bis(pinacolato)diboron (B2pin2) is reported. The reaction proceeded low catalyst loading (0.5 mol %) in the absence N- or P-containing ligands, affording products up to 90% yield. Trifluoracetic acid serves as hydrogen source, enabling synthesis benzylic boronic esters under mild ambient conditions.
