Coupling CO<sub>2</sub> Electroreduction to CO with\nalkyne Alkoxycarbonylation

The alkyne alkoxycarbonylation to α- or β-substituted\nacrylates was coupled with the electrocatalytic reduction of CO<sub>2</sub> to CO. The CO-enriched gaseous mixture produced from the\nelectrocatalytic reduction of CO<sub>2</sub> was collected and directly\nused in the alkyne alkoxycarbonylation. The CO content was found to\nbe critical to the process of carbonylation, and satisfying results\nwere attained by using the gas mixture containing >15 vol % CO.\nThis\nmethod offered an efficient but simple CO source from CO<sub>2</sub> electroreduction to the alkoxycarbonylation reaction in two-compartment\nmanner.
