| titleOfInvention | Methyl-modified cage-type phosphorus ligand, preparation method and application thereof |
| abstract | The invention discloses a methyl-modified caged phosphorus ligand, a preparation method and application thereof, and particularly relates to a methyl-modified caged phosphorus ligand synthesized by further introducing methyl on a benzene ring of triphenylphosphine through synthesis design, wherein when the methyl meta-substituted caged phosphorus ligand is used as a hydroformylation reaction catalyst, the ratio of normal aldehyde to isomeric aldehyde is 2.6, and TOF (time of flight) is 2665h ‑1 The methyl modified cage type phosphorus ligand can more finely regulate and control the space effect and the electronic effect of the ligand from a microenvironment, and the methyl meta-substituted cage type phosphorus ligand has excellent performance, stable property and recoverability, has excellent substrate applicability in hydroformylation catalytic reaction, has better industrial application prospect, and has very important significance in metal organic catalysis. |
