Abstract The chemical use of CO 2 as an inexpensive, nontoxic C1 synthon is utmost topical interest in the context carbon capture and utilization (CCU). We present merger cobalt catalysis electrochemical synthesis for mild catalytic carboxylations allylic chlorides with . Styrylacetic acid derivatives were obtained moderate to good yields functional group tolerance. thus‐obtained products are useful versatile synthons γ‐arylbutyrolactones. Cyclic voltammetry operando kinetic analysis...
Versatile cobalt catalysis enabled electrochemical C–H activation with allenes. Thus, allene annulations were accomplished in terms of C–H/N–H functionalizations excellent levels chemoselectivity, site selectivity, and regioselectivity under exceedingly mild conditions. Detailed mechanistic studies conducted, including reactions isotopically labeled compounds, kinetic investigations, in-operando infrared spectroscopic studies. Further, computational supportive a non-rate-determining cleavage...
Simple, commercially available borane adducts, H3B·THF and H3B·SMe2, have been used to catalyse the hydroboration of alkynes alkenes with pinacolborane give alkenyl alkyl boronic esters, respectively. Alkynes terminal underwent highly regioselective linear ester products. Good functional group tolerance was observed for substrates bearing ester, amine, ether halide substituents. This catalytic process shows comparable reactivity transition-metal-catalysed protocols.
Sulfur-containing molecules are of utmost topical importance towards the effective development pharmaceuticals and functional materials. Herein, we present an efficient mild electrochemical thiolation by cross-electrophile coupling alkyl bromides with functionalized bench-stable thiosulfonates to access sulfides excellent efficacy broad group tolerance. Cyclic voltammetry potentiostatic analysis were performed elucidate mechanistic insights into this electrocatalytic reaction.
