A catalyst system, which contains a) a source of a group VIII metal, and b) a phosphine of general formula: ##STR1## in which R.sup.1, R.sup.2 and R.sup.3 are independently selected from an optionally substituted aryl group and a group of general formula: ##STR2## wherein eachh of A, X, Y and Z is independently selected from a nitrogen atom, a CH group and a group of formula CR wherein R represents a hydroxyl group, an amino group, an amido group, a cyano group, an aryl group, an aryloxy group, a halogen atom, an optionally substituted hydrocarbyl group or an optionally substituted hydrocarbyloxy group, it also being possible for two adjacent CR groups to form a ring, provided that at least one of R.sup.1, R.sup.2 and R.sup.3 represents a group of formula (II) in which at least one of A and Z represents a group of formula CR; or an acid addition salt thereof. Also disclosed is the use of the catalyst system in the selective carbonylation of unsaturated hydrocarbons.
催化剂系统,包含a) VIII族金属的来源,以及b) 通式为:##STR1## 其中R.sup.1,R.sup.2和R.sup.3分别选自可选取代芳基和通式组的群:##STR2## 其中每个A,X,Y和Z分别选自氮原子,CH基团和公式CR的群,其中R代表羟基,氨基,酰胺基,氰基,芳基,芳氧基,卤素原子,可选取代的烃基团或可选取代的烃氧基团,也可以两个相邻的CR基团形成环,前提是R.sup.1,R.sup.2和R.sup.3中至少有一个代表公式(II)的群,其中至少一个A和Z代表公式CR的群; 或其酸加成盐。还公开了在不饱和烃的选择性羰基化反应中使用催化剂系统的方法。
