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 2 15 g of 4-chloro-3-nitrobenzaldehyde, 13.2 g of 4-carboxyphenylboronic anhydride, 10 g of sodium carbonate and a mixture of 50 mg of palladium as 22% strength aqueous chloride solution, 1 ml of water and 820 mg of a 0.6 M aqueous TPPTS solution together with 145 ml of ethylene glycol and 10 ml of water are placed under nitrogen in a reaction vessel and heated to boiling for 4 hours. 200 ml of water are added and the mixture is acidified with concentrated hydrochloric acid to pH 1-2, which results in precipitation of the product. Crystallization from isopropanol and drying under reduced pressure gives 18.4 g (84%) of 4′-formyl-6′-nitrobiphenyl-4-carboxylic acid as a yellow solid having a melting point of 227-235 C.
The synthetic route of 63995-70-0 has been constantly updated, and we look forward to future research findings.
