Embodiment Construction

[0042] Below in conjunction with embodiment the present invention is described in further detail and completely.

[0043] Vinyl biphenol used in the following examples is prepared by the following method, specifically:

[0044] 1) Diphenol preparation of

[0045] Under nitrogen protection, add raw materials to the reaction flask 500mg, C 2 h 3 BF 3 K (943 mg, 7.04 mmol), THF (18 mL), heated to reflux for 24 hours, and the product was separated and purified by column chromatography. The obtained product (200 mg), methanol (6.2 mL), water (3.1 mL) and saturated NaHCO 3 (6.2 mL) was further added into the reaction flask, and the mixture was heated to 50° C. and reacted for 5 hours. The obtained crude product was separated and purified by column chromatography to obtain vinyl biphenol. The product is characterized as follows: 1 H NMR (500MHz, CDCl 3 )δ7.41(dd, J=10.0,1.5Hz,2H),7.32(d,J=1.5Hz,2H),7.00(d,J=10.0Hz,2H),5.69(dd,J=17.5,11.0 Hz, 2H), 5.65(d, J=17.05Hz, 2H), ...

Abstract

The invention discloses a kind of porous organic polymer containing bidentate phosphoramidite ligand, its preparation method and application. The polymer has the following general formula I: the above polymer is obtained by performing polymerization reaction with the compound of the general formula. After the porous organic polymer with bidentate phosphoramidite ligand provided by the present invention forms a catalyst with a transition metal salt, it can be used for the hydroformylation reaction of terminal olefins or the isomerization-hydroformylation reaction of internal olefins, And it has high catalytic rate, good selectivity and recyclability, and has practical value.

Description

technical field [0001] The present invention relates to a kind of organic polymer and its preparation method and application. Specifically, it relates to a class of porous polymers containing bidentate phosphoramidite ligands and their preparation methods and applications, belonging to the technical field of organic chemistry. [0002] technical background [0003] Hydroformylation refers to alkenes and CO / H 2 The process of forming aldehydes under the action of a catalyst. Olefin hydroformylation is an important method for industrial synthesis of aldehydes. Aldehydes are very valuable fine chemicals and important synthetic intermediates. The realization of heterogeneously catalyzed hydroformylation of olefins can effectively solve the problems of catalyst recovery, recycling and pollution. Realize the heterogeneity of homogeneous catalysts, mainly including liquid / liquid two-phase and solid-supported catalytic systems. France -Poulenc Company and German Ruhrchemie Comp...
