Nickel-catalyzed arylcarboxylation of alkynes with arylmagnesium reagents and carbon dioxide (CO2, 1 atm) was realized in one pot. Various trisubstituted acrylic acids within an aryl group at the β-position have been prepared efficiently with good regioselectivity under mild conditions. The resulting products could be further transformed to benzoannelated cycles retaining CO2 as a one-carbon synthon
在一锅中用芳基镁试剂和二氧化碳(CO 2,1 atm)实现了炔烃的镍催化的芳基羧化反应。在温和条件下,已经以良好的区域选择性有效地制备了在β-位的芳基内的各种三取代的丙烯酸。可以将所得产物进一步转化为苯甲酰化循环,保留CO 2为一碳合成子。
