Xantphos Doped POPs-PPh3 as Heterogeneous Ligand for Cobalt-Catalyzed Highly Regio- and Stereoselective Hydrosilylation of Alkynes

A Co(acac)2/POL-Xantphos@10PPh3-catalyzed hydrosilylation of unsymmetrical internal alkynes with Ph2SiH2 has been developed for the synthesis of highly selective syn-α-vinylsilane products. Furthermore, terminal alkynes were also used and gave the products with excellent regioselectivity and a wide functional group tolerance. Because this porous organic polymer combines the selectivity and activity merits of Xantphos with the stability advantage derived from the high concentration of PPh3, the Co(acac)2/POL-Xantphos@10PPh3 can be recycled multiple times without loss of activity and selectivity. This heterogeneous catalyst is expected to find promising applications in industrial synthesis.

Method for high selectively preparing aldehyde by using olefin

The invention discloses a method for high selectively preparing an aldehyde by using an olefin. According to the method, an organic polymer self-load type catalyst is used, an olefin hydroformylationreaction is applied to high selectively preparation of an aldehyde. According to the organic polymer self-load catalyst, one, two or three metals selected from a group consisting of Rh, Co, Pd and Irare used as active components, and a phosphine-containing organic copolymer is used as a carrier, wherein the phosphine-containing organic copolymer carrier is formed by copolymerization of a polydentate organic phosphine ligand and a monodentateorganic phosphine ligand. The organic polymer self-load catalyst provided by the invention is suitable for reactors such as fixed beds, slurry beds, bubbling beds, trickle beds and the like, and has good performance in a reaction of high selectively preparing the aldehyde through the olefin hydroformylation reaction; the aldehyde with a high normal-specific ratio can be produced, wherein the positive-specific ratio can reach 25 or above; side reactions are few; and the alkane content of an obtained product is 1% or below. The multi-phase catalyst is good in stability, and the separation of the catalyst from the reactants and products is simple and efficient.

Palladium-metalated porous organic polymers as recyclable catalysts for chemoselective decarbonylation of aldehydes

A novel palladium nanoparticle (NP)-metalated porous organic ligand (Pd NPs/POL-xantphos) has been prepared for the chemoselective decarbonylation of aldehydes. This heterogenous catalyst not only has excellent catalytic activity and chemoselectivity, but also holds high activity after 10 runs of reuse. The effective usage of this method is demonstrated through the synthesis of biofuels such as furfuryl alcohol (FFA) via the highly chemoselective decarbonylation of biomass-derived 5-hydroxy-methylfurfural (HMF) with a TON up to 1540. More importantly, 9-fluorenone could be obtained in one step through the decarbonylation of 2-bromobenzaldehyde by using this heterogeneous catalyst.
