摘要：

The palladium-catalyzed, atmospheric-pressure carboxylation of allylic halides occurs readily in an aqueous sodium hydroxide/organic solvents two-phase system, giving beta,gamma-unsaturated acids. Phosphine complexes [PdCl2L2] (I, L=m-(Ph2P)C6H4SO3Na; II, L=Ph3P) or Na2[PdCl4] (III) can be used as the catalyst. Atmospheric-pressure alkoxycarbonylation is realized under the influence of a homogeneous alcoholic solution of sodium alkoxide. Phosphine-free palladium complexes, such as [(pi-allyl)PdCl]2 or III, are the favored catalyst. Beta,gamma-Unsaturated esters are obtained in high yields.
