4054-67-5, name is 3,3′,5,5′-Tetramethyl-1H,1’H-4,4′-bipyrazole, belongs to pyrazoles-derivatives compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Recommanded Product: 4054-67-5
A mixture of Co(CH3COO)2·4H2O (0.050 g, 0.20 mmol), H2bpdc (0.072 g, 0.30 mmol) and H2bpz (0.038 g, 0.20 mmol) in DMF (5 mL) and CH3CN (5 mL) was placed in a Teflon-lined stainless steel vessel (15 mL). The vessel was heated at 140 C for 72 h, then slowly cooled to room temperature. The purple crystals of 1 were isolated by filtrating, washing with DMF, and dried in vacuo. Yield: 24 mg (23.4%). Anal. Calcd for C44H54Co2N6O15: C, 51.57; H, 5.31; N, 8.20%. Found: C, 51.45; H, 5.17; N, 8.11%. IR (KBr, cm-1): 3426(vs), 2919(w), 1680(s), 1605(s), 1540(m), 1394(s), 1297(m), 1172(w), 1130(w), 851(m), 765(s).
The synthetic route of 4054-67-5 has been constantly updated, and we look forward to future research findings.
