330680-46-1, Trimethyl [2,2′:6′,2”-terpyridine]-4,4′,4”-tricarboxylate is a catalyst-ligand compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

1.3g of the compound of the d-1-6 with one equivalent ofCompound d-1-7 NMP (N- methyl pyrrolidone) was stirred for 3 hours in the atmosphere of nitrogen at 70 was added to 150ml. Then compound d-1-8 by the addition of 1 eq., Was stirred at 160 time Heating 8, by the addition of 10 eq of ammonium Ansan between arylthio was stirred at 160 8 hours. After concentration of the resulting solution, by addition of water and filtered. Purification of the filtered water to the silica gel column chromatography, and then the obtained compound d-1-9, was added to a mixed solvent of 30ml of acetone and 40ml 1N sodium hydroxide aqueous solution, was stirred for 24 hours at an external temperature of 65 . It returned to room temperature, adjusted to pH 3 with hydrochloric acid and filtered the precipitate to give 2.5g of crude D-1-5a.

The synthetic route of 330680-46-1 has been constantly updated, and we look forward to future research findings.

To 150 mL of NMP (N-methylpyrrolidone), 1.22 g of compound d-1-7 and 1.62 g of compound d-1-6 were added, followed by stirring at 70 C. for 3 hours under a nitrogen atmosphere. Then, 1.63 g of compound d-1-8 was added thereto, followed by stirring under heating at 160 C. for 8 hours. Then, 10.7 g of ammonium thiocyanate was added thereto, followed by stirring at 160 C. for 8 hours. After concentration, water was added, followed by filtration. The filtrate was purified by a silica gel column chromatography to obtain compound d-1-9, followed by adding the obtained compound to a mixed solvent of 30 mL of acetone and 40 mL of a 1N sodium hydroxide aqueous solution, and stirring for 24 hours at external temperature of 65 C. After bringing the temperature to room temperature, the pH was adjusted to 1.5 with hydrochloric acid, and the precipitate was filtrated, to give 3.3 g of crude product D-1-1a. (0270) This was dissolved in a methanol solution together with TBAOH (tetrabutylammonium hydroxide), and purified by SephadexLH-20 column. The fraction of the main layer was collected and concentrated, and then a solution of 0.1M trifluoromethanesulfonic acid was added thereto so as to adjust the pH thereof to 3, and the precipitate was filtered, thereby obtaining 2.4 g of exemplified dye D-1-1a. (0271) The structure of exemplified dye D-1-1a obtained was confirmed by MS measurement. (0272) MS-ESI m/z=928.1 (M-H)+

330680-46-1 Trimethyl [2,2′:6′,2”-terpyridine]-4,4′,4”-tricarboxylate 66776557, acatalyst-ligand compound, is more and more widely used in various.
