CATALYSIS OF HYDROSILYLATION XI. RHODIUM(I)-SILOXYALKYLPHOSPHINE COMPLEXES; SYNTHESIS, CHARACTERISTICS AND CATALYTIC ACTIVITY

Rhodium(I) complexes with 1,5-cycloocatdiene (COD) and disiloxydiphosphines 2 where n = 1-3; (B-1, B-2, B-3, respectively)> and/or with trisiloxytriphosphine Ph2P(CH2)3(CH3)Si2 (C-2) were synthesized.Their composition and structure were determined using elemental analysis, molecular weight measurements and spectroscopic (IR, 1H NMR and vis) methods, and were then compared with the corresponding data for RuCl(COD)PPh3 (A) and RhCl(COD)2 (D).The analyitical and physico-chemical data all confirm the square planar geometry of the rhodium siloxyphosphine (the same as for rhodium triphenylphosphine) complexes with the general formula mZ where m =2 and Z =(CH3)2SiOSi(CH3)2 or m = 3 and Z = (CH3)2SiOSi(CH3)OSi(CH3)2. The structure is independent of the type of phosphine ligand, and the molar ratio of Rh : P is always 1 : 1. Catalytic activity of the complexes prepared was tested in the hydrosilylation of 1-hexene by triethoxysilane which showed a slight decrease in turnover number (A-C) compared with Wilkinson's catalyst (E) but the activation energies for the rhodium-siloxyphosphine complexes (B and C) are higher than those for the rhodium phosphine complexes (A and E).

Solvent-free hydrosilylation of alkenes and alkynes using recyclable platinum on carbon nanotubes

Platinum nanoparticles were stabilized at the surface of carbon nanotubes and the nanohybrid was valorized as a catalyst for the hydrosilylation of alkenes and alkynes. The heterogeneous catalyst operated under sustainable conditions (room temperature, no solvent, low catalyst loading, air atmosphere) and exhibited improved stabilty as recycling and reuse could be achieved for multiple consecutive reactions.

Photo-initiation hydrosilylation reaction method

The invention discloses a photo-initiation hydrosilylation reaction method, and relates to a method for hydrosilylation. The method comprises the following steps: (1) using olefin and hydrogen-containing silane as reaction raw materials, or using vinyl polysiloxane and hydrogen-containing polysiloxane as reaction raw materials; and (2) performing a hydrosilylation reaction on the reaction raw materials under illumination conditions and under the action of a photo-initiation catalyst, wherein the photoinitiator is an aroylphosphine oxide compound, a co-initiator catalyst is also included in thephoto-initiation hydrosilylation reaction method, the co-initiator is cuprous halide, and the molar ratio of the haloaroylphosphine oxide compound to the cuprous halide is (1:0.01)-(1:1); and the light source for the illumination condition is ultraviolet light, and the molar ratio of olefinic bonds in the olefin or vinyl silicone oil to the aroylphosphine oxide compound is (400:1)-(100:1). Through the method, use of precious metal catalysts is avoided, the reaction conditions are mild, the system needs no heating, and reduction of energy consumption is facilitated; and the method has good universality of the reaction substrate, and the catalytic system has a wide source and easy storage.

Preparation, characterization and evaluation of a series of heterogeneous platinum catalysts immobilized on magnetic silica with different acid ligands

Platinum was immobilized on magnetic silica gel by means of boronic, nitric, carboxylic or sulfuric acid ligands to give four heterogeneous Pt nano-catalysts, designated as Fe3O4@SiO2-BA@Pt, Fe3O4@SiO2-NA@Pt, Fe3O4@SiO2-CA@Pt and Fe3O4@SiO2-SA@Pt, respectively. Particles of these mono-dispersible Pt catalysts were 10–20?nm in size and could be separated for recycling by means of a magnet. Fe3O4@SiO2-BA@Pt (0.174?mmol/g Pt) showed the best catalytic activity and selectivity, which were better than Speier’s catalyst. Its turnover numbers were up to 1.7 × 106 and 1.1 × 106 for hydrosilylation of 1-hexene or styrene, respectively. This material could also catalyze the hydrosilylation of a broad range of alkenes and alkynes as substrates and methyldichlorosilane or triethoxysilane as silanes. Similar yields of 1-hexyl-methyldichlorosilane at the first and eighth runs (96.5% and 95.2%, respectively), together with a final Pt content of 0.171?mmol/g indicated the outstanding stability of Fe3O4@SiO2-BA@Pt under the catalytic reaction conditions.
