A catalyst system, which comprises
a) a source of a Group VIII metal, and
b) a phosphine of general formula:
in which R¹, R² and R³ are independently selected from an optionally substituted aryl group and a group of general formula:
wherein each 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 R¹, R² and R³ 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 are novel phosphines, and the use of the catalyst system in the selective carbonylation of unsaturated hydrocarbons.
催化剂系统,包括
a) 第 VIII 族金属源,和
b) 通式为
其中 R¹、R² 和 R³ 分别独立地选自任选取代的芳基和通式如下的基团:
其中 A、X、Y 和 Z 各自独立地选自一个氮原子、一个 CH 基团和一个通式为 CR 的基团,其中 R 代表羟基、氨基、酰胺基、氰基、芳基、芳氧基、卤素原子、任选取代的烃基或任选取代的烃氧基,相邻的两个 CR 基团也可以形成一个环,条件是 R¹、R² 和 R³ 中至少有一个代表式 (II) 的基团,其中 A 和 Z 中至少有一个代表式 CR 的基团;或其酸加成盐。
此外,还公开了新型膦以及该催化剂体系在不饱和烃选择性羰基化中的用途。
