The important role of Ferrocenylacetic acid

With the complex challenges of chemical substances, we look forward to future research findings about Ferrocenylacetic acid

Name is Ferrocenylacetic acid, as a common heterocyclic compound, it belongs to iron-catalyst compound, and cas is 1287-16-7, its synthesis route is as follows.,1287-16-7

General procedure: A mixture of ferrocene acetic acid (1 mmol), the required 3-substituted-4-amino-5-mercapto-1,2,4-triazole(1 mmol), and p-toluenesulfonic acid (0.1 mmol) in DMF(10 mL) was stirred until a homogeneous solution was obtained. The mixture was exposed to microwave irradiation for about 3 min at 350 W and then cooled and poured into crushed ice. The mixture was adjusted to pH 7 with potassium carbonate and potassium hydroxide and then kept overnight at room temperature. The crude product was filtered off, dried and recrystallized from 80% ethanol to afford the pure product (Scheme 1). 6-Ferrocene methylene-1,2,4-triazolo[3,4-b]-1,3,4-thiadiazole (1a) Brown solid; Yield: 82%; m.p.: 165-168 C; IR (KBr, nu/cm-1): 3085 (s), 2920 (m), 1604 (s), 656 (m), 487 (m); 1HNMR (CDCl3, 400 M, delta, ppm): 9.98 (s, 1H, N=CH), 4.30(s, 2H, C5H4),4.25 (s, 2H, C5H4),4.16 (s, 5H, C5H5),2.20(s, 2H, CH2);13C NMR (CDCl3, 100 M, delta, ppm): 167.6,161.0, 160.4, 137.2, 130.2, 121.3, 32.1; Anal. Cald. forC14H12N4SFe:C, 51.85; H, 3.70; N, 17.28; Found C, 51.68;H, 3.59; N, 17.51%.
