IONIC SALTS

摘要

An ionic salt comprising at least one organo cation and at least one anion characterised in that the anion is of the formula [BX3Y]<->, wherein X is a halogen and Y is selected from: (a) a halogen other than X, (b) an OR group wherein R is a C1-C30 hydrocarbyl group, (c) an -O(O)CL group in which L is hydrogen or a hydrocarbyl group and (d) an -O(O)CZ group where Z is a carboxylic, hydroxycarboxylic or a hydrocarbylene carboxylic group. The ionic salts may be used in combination with certain metal salts or complexes as catalysts for reactions such as hydroformylation, olefin polymerisation and hydrogenation.
