A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 1038-95-5, Name is Tri-p-tolylphosphine, molecular formula is C21H21P. In a Patent£¬once mentioned of 1038-95-5, category: chiral-phosphine-ligands
A cadmium sulfide catalytic bioprosthetic heart preparation method of the compound (by machine translation)
The invention relates to medicine and the natural compound chemical intermediate and related chemical technical field, relates to a cadmium sulfide catalytic bioprosthetic heart preparation method of the compound. The invention is characterized in that the phosphine compound with the 3 – substituted – 1, 4, 2 – two-oxazole – 5 – ketone as a raw material, in order to cadmium sulfide as a catalyst, under the illumination condition, a step construction phosphorus triazene compound. Wherein the 3 – substituted – 1, 4, 2 – two-oxazole – 5 – ketone compound in a solvent in molar concentration is 0.01 – 2mmol/mL, with the catalyst in a molar ratio of 1: 0.01 – 1: 0.5. The invention has the advantages that the reaction uses photocatalytic reaction, clean and pollution-free, mild reaction conditions, operation and after treatment is simple, the substrate has good compatibility.
