Carbonylation of terminal alkynes was performed using a new triple catalytic system, Pd(II)/chlorohydroquinone/NPMoV, under carbon monoxide and oxygen. For instance, phenylacetylene was converted into methyl phenylpropiolate (85%) in methanol and phenylmaleic anhydride (62%) in dioxane. The reaction did not take place in the absence of oxygen.
