Nonaqueous ionic ligand liquids, process for preparing them and their use as catalyst constituents

摘要

Nonaqueous ionic ligand liquids of the formula (Q(+))a Aa-, where Q(+) is a singly charged quaternary ammonium and/or phosphonium cation or the equivalent of a multiply charged ammonium and/or phosphonium cation and Aa- is a sulfonated triarylphosphine, a process for preparing them and their use as catalyst constituents.
