Reference of 22013-33-8, Chemical Research Letters, May 2021. The appropriate choice of redox mediator can avoid electrode passivation and overpotential, which strongly inhibit the efficient activation of substrates in electrolysis. 22013-33-8, Name is 2,3-Dihydrobenzo[b][1,4]dioxin-6-amine,introducing its new discovery.
A mild protocol has been developed for the PdII-catalyzed alkoxycarbonylation of terminal olefins to produce alpha,beta-unsaturated esters with a wide range of substrates. Key features are the use of MeCN as solvent (and/or ligand) to control the reactivity of the intermediate Pd complexes and the combination of CO with O2, which facilitates the CuII-mediated reoxidation of the Pd0 complex to Pd II and prevents double carbonylation. Acetonitrile is the key!
