63995-70-0, Sodium 3,3′,3”-phosphinetriyltribenzenesulfonate is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,63995-70-0
Example 4 15 g of 2-chlorobenzonitrile, 14.8 g of p-tolueneboronic acid and 28.9 g of sodium carbonate together with 50 ml of p-xylene, 40 ml of DMSO and 10 ml of water are heated to 120 C. At 80 C., a mixture of 24.7 g of palladium acetate and 0.55 ml of 0.6 M aqueous TPPTS solution in 2.5 ml of DMSO is added. After the reaction is complete, the phases are separated. The aqueous phase is washed with 50 ml of xylene. The combined organic phases are washed with 20 ml of water and dried over sodium sulfate. The solvent is evaporated and the residue is crystallized from n-heptane. This gives 18.6 g (88%) of 4′-methylbiphenyl-2-carbonitrile having a melting point of 48-49 C.
63995-70-0 Sodium 3,3′,3”-phosphinetriyltribenzenesulfonate 6099338, achiral-phosphine-ligands compound, is more and more widely used in various fields.
