    • Unconjugated olefins having at least two hydrogens substituted at the olefinic carbon atoms, free of amine groups and free of hydroxyl or halogen substituents at carbon atoms Alpha and Beta to the unsaturation can be carboxylated or carboalkoxylated by reaction with carbon monoxide and water or an alcohol in the presence of a catalyst L2MXY where M is Pd or Pt, X and Y alike or different are chlorine, bromine, iodine, alkyl, cyano, -SnCl3, alkanoyl or aroyl, and when X and Y are different X can also be H, and L is a phosphinite, phosphonite, thiophosphinite or dithiophosphonite ligand.
    • 在烯属碳原子上具有至少两个不含胺基团并且在不饱和键的α和β的碳原子处不含羟基或卤素取代基的氢的未共轭的烯烃可以通过与一氧化碳和水或醇的反应而被羧化或进行碳烷氧基化 其中M是Pd或Pt,X和Y的催化剂L2MXY的存在是氯,溴,碘,烷基,氰基,-SnCl 3,烷酰基或芳酰基,当X和Y不同X时,也可以是H, L是亚磷酸盐,亚膦酸盐,硫代膦酸盐或二硫代亚膦酸盐配体。
