POROUS ORGANIC CAGE LIGAND CONTAINING P AND N AND COMPLEX CATALYST AND APPLICATION

摘要

The present invention relates to a porous organic cage ligand containing P and N and preparation method for the porous organic cage ligand, and application of a corresponding complex catalyst in hydroformylation of olefin. A catalyst formed by the P and N porous organic cage ligand and a transition metal is in a homogeneous phase reaction state during reaction, reactants and catalytic centers are in full contact, and a good catalytic performance is ensured; an alcohol solvent is added after the reaction is finished, the P and N porous organic cage ligand complex catalyst is crystallized from a reaction system, and recycling of a catalyst is simply achieved. The porous organic cage ligand containing P and N is formed by crosslinking by using P and N ligands of which functional groups such as an aldehyde group and an amino group are functionalized as monomers and using corresponding polyamine or polyaldehyde as a comonomer. A complex catalyst formed by the P and N porous organic cage ligand and the transition metal in the present invention has a good performance in hydroformylation, a TOF value of the catalyst can reach 3000 h^-1 or more, the selectivity of alkane of the obtained products is less than 1%, and the selectivity of aldehyde is 90% or more.
