The invention relates to a catalyst system, which comprises a) a source of a Group VIII metal, and b) a polyphosphine of general formula:
in which each R is independently selected from an optionally substituted alkyl, cycloalkyl, aryl or heteroaryl group; and each of A, X and Z is independently selected from a nitrogen atom, a CH group, a group of formula C-PR₂ with R being defined as hereinbefore, and a group of formula CR', wherein R' represents a hydroxyl group, an amino group, an amido group, a cyano group, an acyl group, an acyloxy group, a halogen atom, an optionally substituted hydrocarbyl group, an optionally substituted heteroaryl group or an optionally substituted hydrocarbyloxy group, it also being possible for two adjacent CR' groups to form a ring; or an acid addition salt thereof. The invention further relates to the use of this catalyst system in the carbonylation of unsaturated compounds.
本发明涉及一种催化剂体系,它包括 a) 第 VIII 族金属源和 b) 通式的聚磷酸盐:
其中每个 R 独立地选自任选取代的烷基、环烷基、芳基或杂芳基;A、X 和 Z 各自独立地选自一个氮原子、一个 CH 基团、一个式 C-PR₂ 的基团(其中 R 的定义如前)和一个式 CR' 的基团,其中 R' 代表一个羟基、一个氨基、一个酰胺基、一个氰基、一个酰基、一个酰基基团、一个酰基基团、一个酰基基团、酰基、酰氧基、卤原子、任选取代的烃基、任选取代的杂芳基或任选取代的烃氧基,两个相邻的 CR' 基团也可形成一个环;或其酸加成盐。本发明还涉及将这种催化剂体系用于不饱和化合物的羰基化。
