Triphenylphosphine derivative ligands with large steric hindrance as well as preparation method and application of triphenylphosphine derivative ligands

The invention discloses a triphenylphosphine derivative ligand with large steric hindrance as well as a preparation method and application thereof, and the specific method is as follows: through a synthetic reaction, different substituted aryl groups and cycloalkane groups are connected on a basic structure of triphenylphosphine by using imine bonds to obtain the triphenylphosphine derivative ligand with large steric hindrance. By introducing different substituted aromatic imine groups and cycloalkane imine groups, the steric hindrance effect of the whole ligand is remarkably enhanced, and the stereoselectivity and reaction activity of hydroformylation reaction are greatly improved. The substituted derivative phosphine ligand connected by the imine bond has very excellent catalytic performance parameters, is wide in substrate application in hydroformylation reaction, stable in property, good in stereoselectivity and convenient to recycle, has improved catalytic performance, and has a good industrial application prospect.

Triphenylphosphine-Based Covalent Organic Frameworks and Heterogeneous Rh-P-COFs Catalysts

The synthesis of phosphine-based functional covalent organic frameworks (COFs) has attracted great attention recently. Herein, we present two examples of triphenylphosphine-based COFs (termed P-COFs) with well-defined crystalline structures, high specific surface areas, and good thermal stability. Furthermore, rhodium catalysts with these P-COFs as support material show high turnover frequency for the hydroformylation of olefins, as well as excellent recycling performance. This work not only extends the phosphine-based COF family, but also demonstrates their application in immobilizing homogeneous metal-based (e.g., Rh-phosphine) catalysts for application in heterogeneous catalysis.

Synthesis, X-ray geometry, and anodic behavior of tris[2-(hydroxymethyl)phenyl]phosphane

Tris[(monohydroxymethyl)phenyl]phosphanes 5a and 5b were prepared, and the geometry of the ortho-isomer 5a was determined by X-ray diffraction. 5a was found to be propeller-like in shape, exhibiting a helical conformation with the three hydroxymethyl subs
