(E)- or (Z)-Enynoic acids and (2E,4E)- or (2Z,4E)-dienoic acids can be obtained in good yields under mild conditions through palladium-catalysed cross coupling of (E)- or (Z)-3-iodoprop-2-enoic acid with alkynylzinc or vinyltin reagents.
(E)-或(Z)-烯炔酸以及(2E,4E)-或(2Z,4E)-二烯酸可以在温和条件下通过钯催化的交叉偶联反应,从(E)-或(Z)-3-碘丙-2-烯酸与炔基锌或乙烯基锡试剂获得,产率良好。
