在PdL(2)、KI和空气存在下，在25-80℃的温度下，在温和的条件下，用一氧化碳、醇或水处理炔烃，可以很容易地实现末端炔二羰化反应，具有前所未有的催化效率。二碳酰化产物主要是马来酸酯或酸及其环链互变异构体。后者很大程度上是在室温下形成的。对反应途径进行了讨论。
Terminal alkyne dicarbonylation can be readily effected under mild conditions by treating alkynes with carbon monoxide and alcohols or water at 25-80 degrees C in the presence of Pdl(2), KI and air, with unprecedented catalytic efficiency. Dicarbonylated products are mainly maleic esters or acids and their ring-chain tautomers. The latter are formed to a large extent at room temperature. Reaction pathways are discussed.
