Definitions
- Tricyclic phosphine-phosphinites and their use in catalysis
- the present invention includes new asymmetrical chiral phosphine-phosphinites and their synthesis as well as complexes of these compounds with metals of the groups Vllb Vlllb and Ib of the periodic table and their use as catalysts for enantioselective transformations, especially for hydrogenations.
- Trisubstituted organophosphorus compounds are of great importance as ligands in homogeneous catalysis.
- the electronic and steric properties of the phosphorus ligand can be influenced in a targeted manner by varying the substituents on the phosphorus in such compounds, so that selectivity and activity can be controlled in homogeneous catalytic processes.
- Enantiomerically enriched chiral ligands are used in asymmetric synthesis or asymmetric catalysis. Here it is essential that the electronic and stereochemical properties of the ligand are optimally matched to the respective catalysis problem. There is therefore a great need for chiral ligands that differ stereochemically and electronically in order to find the “tailor-made” ligand that is optimal for a particular asymmetric catalysis.
- the structural diversity of the phosphorus ligands known to date is very large. These ligands can be classified according to substance classes, for example, and examples of such substance classes are trialkylphosphines and triarylphosphines, phosphites, phosphinites, phosphonites, aminophosphanes, etc. This classification by substance classes is particularly useful for describing the electronic properties of the ligands. In addition, a classification of phosphorus ligands according to their symmetry properties or according to the denticity of the ligands is possible. This structuring takes into account in particular the stability, activity and stereoselectivity of metal complexes with phosphorus ligands as catalyst precursors or as catalysts.
- unsymmetrical bidentate organophosphorus ligands are increasingly becoming the focus of asymmetric catalysis.
- Important examples are the large class of versatile chiral ferrocenylphosphine ligands such as JOSIPHOS, DPPM, the bisphosphinite ligands such as CARBOPHOS, which are particularly successfully used in the asymmetric hydrogenation of olefins and imines, or the phosphine-phosphite ligands such as BINAPHOS, which are used in the asymmetric Hydroformylation of olefins can be used successfully.
