554-95-0,554-95-0, Benzene-1,3,5-tricarboxylic acid is a catalyst-ligand compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

Trimesic acid (5 g, 23.8 mmol) was suspended in methanol (15 mL) and heated to reflux. When a clear solution obtained,1.6 mL of con.H2SO4 was added slowly and the mixture was refluxed for 6 h. After 3 h, white solid get precipitated from the solution. The mixture was cooled to room temperature, slowly neutralized with saturated NaHCO3 solution, filtered and washed with excess water until the aqueous layer turned neutral. It was then dried to yield a white solid of trimethyl-1,3,5-benzenetricarboxylate (5.72 g). LiAlH4 tablets (2.5 g, 66 mmol) were suspended and refluxed in dry THF (50 mL) under an inert N2 atmosphere. Trimethyl-1,3,5-benzenetricarboxylate (5 g, 20 mmol) was dissolved in 100 mL dry THF and added to the suspension in 1 h. The solution was then refluxed for 24 h, cooled to 0 C and acidified with 1MHCl. THFwas removed under reduced pressure and the aqueous suspension (100 mL) thus obtained was extracted with ethyl acetate for 48 h in a liquideliquid extractor to yield 1,3,5-trimethylolbenzene which appeared as colorless crystals in room temperature. The mother liquor was concentrated to yield second fraction. Both the fractions were NMR pure and the combined yield was 4.96 g.

The synthetic route of 554-95-0 has been constantly updated, and we look forward to future research findings.

554-95-0,With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.554-95-0,Benzene-1,3,5-tricarboxylic acid,as a common compound, the synthetic route is as follows.

General procedure: Reaction of AgNO3 (33.4 mg, 0.2 mmol), pyridazine (pdz) (16.0 mg, 0.2 mmol) and 1,3,5-benzene tricarboxylic (H3btc) (44.2 mg, 0.2 mmol) took place in H2O-DMF (N,N-Dimethylformamide) solvents (6 ml, v/v = 1:1) in the presence of ammonia (0.5 mL, 14 M) under ultrasonic treatment (160 W, 40 kHz,30 min) at 40 C. The resultant colourless solution was allowed slowly to evaporate at room temperature in the dark. The yellow crystals of complex 1 were obtained after several days.The crystals were isolated by filtration and washed by deionized water and ethanol and dried in the air. Yield based on Ag is 88% .Elemental analysis: Anal. Calc. for Ag6C26H14N4O12: C, 25.563; H,1.155; N, 4.586. Found: C, 25.37; H, 1.19; N, 4.65%. Selected IR peaks (cm1): 3283 (s), 2264 (w), 1863 (w), 1614 (s), 1557 (s),1417 (s), 1360 (s), 1099 (m), 1060 (w), 972 (w), 920 (w), 767 (s), 716 (s), 660 (w), 514 (m), 455 (w).

As the paragraph descriping shows that 554-95-0 is playing an increasingly important role.
