Verfahren zur Herstellung von sekundären Aminen

摘要

The invention provides a process for the preparation of a secondary amine which comprises reacting carbon monoxide, hydrogen, a polyolefin and a primary amine derivative having a terminal -NH<6> group and a terminal -NR<1>R<2> group, wherein each of R<1> and R<2> independently represents a hydrogen atom or an alkyl group; in the presence of a suitable solvent and a catalyst system comprising a source of cationic rhodium; optionally a source of cationic ruthenium; an aromatic N-heterocyclic ligand and a source of an anion other than a halide.
