Abstract

The invention discloses a spiroketal frame bidentate phosphoramidite ligand as well as a preparation method and an application thereof. The ligand is the compound shown in a formula I or II or the enantiomer, racemate or diastereoisomer of the compound; and the ligand is prepared by condensation reaction of the compound in the formula I or II, and phosphorus-chlorine compounds. The spiroketal frame bidentate phosphoramidite ligand disclosed by the invention and transition metal salt form a complex, and the complex can be used for terminal olefine hydroformylation or isomerization-hydroformylation of internal olefins; and moreover, the spiroketal frame bidentate phosphoramidite ligand has high catalytic rate, good selectivity and practical value.

Description

technical field

[0001] The present invention relates to a class of bidentate phosphoramidite ligands and their preparation methods and applications. Specifically, they relate to a class of bidentate phosphoramidite ligands with a spiroketal skeleton and their preparation methods and applications, belonging to the technical field of organic chemistry . Background technique

[0002] Phosphorus ligands are the most studied and widely used ligands so far. According to the different atoms connected to P, phosphorus ligands can be divided into phosphine ligands in which P is connected to three carbon atoms, P and one or more O Atom-linked phosphite ligands and phosphoramidite ligands containing P linked to one or more N atoms. Phosphoramidite ligands have been developed rapidly in the past ten years due to their stable structure, simple synthesis, easy modification, and unique effects. Infused with new vitality. The phosphoramidite ligand structure can be divided into two parts...
