- Synthesis method of trihexylphosphine
-
The invention discloses a synthesis method of trihexylphosphine, belonging to the field of compound preparation. The synthesis method comprises the following steps: firstly reacting chlorohexane and magnesium chips under the protection of nitrogen gas in a mixed solvent of toluene and tetrahydrofuran by taking iodine granules as an initiator so as to obtain hexyl magnesium chloride; and without purification, cooling the hexyl magnesium chloride, directly adding phosphorus trichloride to the hexyl magnesium chloride, stirring for reacting at low temperature, and after the reaction, directly carrying out reduced pressure distillation to obtain the trihexylphosphine product. The purity of the trihexylphosphine product is more than 99%, and the yield of the trihexylphosphine product is 92.6%; and the solvent used in the synthesis method is easy to recycle.

- Electrocatalytic eco-efficient functionalization of white phosphorus
-
The novel eco-efficient methods to transform white phosphorus into the esters of phosphoric, phosphorous and phosphonic acids, tertiary phosphines and other organophosphorus compounds under conditions of electrochemical catalysis were elaborated. The mechanism of these processes was investigated using the method of cyclic voltammetry and preparative electrolysis.

- Method for manufacturing acryloxypropysilane
-
A method to manufacture acryloxypropylsilane to a high degree of purity is achieved by hydrosilation of (A) allyl acrylate or allyl methacrylate by (B) a hydrosilane compound, using (C) a platinum-containing compound as the catalyst and (D) an organic phosphorus compound as the promoter. The acryloxypropylsilane product is expressed by General Formula I where R1 represents a hydrogen or methyl group, R2 represents a hydrolyzable group, R3 represents an aryl, alkenyl or aryl group of carbon number 1-12, and n is 0, 1, 2, or 3.

- Process for preparing organophosphines
-
Olefins can be induced to react with phosphines at ambient temperature and pressure to produce organophosphines by free-radical addition. Suitable olefins include C1 to C4 alpha-olefins, cyclic olefins, polycycloalkenyl species, allyl alcohol and esters of vinyl phosphonic acid.
