A process for the hydroformylation of less reactive olefins with hydrogen and carbon monoxide in the presence of a hydroformylation catalyst which has been modified by a ligand of formula L(OR1)(OR2)(OR3), wherein L represents P or As and R1, R2 and R3 are (dis)similar aryl groups provided that at least one of R1, R2 and R3 is a group
wherein Q represents a group
or a group
wherein H4 is an optionally tluorine-substituted hydrocarbyl group, R5 is H or R4, R' is H or an inert substituent on the meta and/or the para position of the ring, X is oxygen or sulphur, n is 0 or 1, and R7 represents a hydrogen atom or an inert substituent. Less reactive olefins such as limonene can be hydroformylated with very good results.
一种在经式 L(OR1)(OR2)(OR3)配位体修饰的加氢甲酰化催化剂存在下用氢气和一氧化碳对活性较低的烯烃进行加氢甲酰化的工艺,其中 L 代表 P 或 As,R1、R2 和 R3 是(不)相似的芳基,条件是 R1、R2 和 R3 中至少有一个是基团
其中 Q 代表一个基团
或一个基团
其中 H4 是可选的氟代烃基,R5 是 H 或 R4,R'是 H 或环的元和/或对位上的惰性取代基,X 是氧或硫,n 是 0 或 1,R7 代表氢原子或惰性取代基。活性较低的烯烃(如柠檬烯)也可以进行氢甲酰化,而且效果非常好。
