These common heterocyclic compound, 492-98-8, name is 1H,1’H-2,2′-Biimidazole, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. Product Details of 492-98-8
A mixture of Zn(NO3)2 6H2O (44.6mg,0.15mmol),5-Brnic(60.6 mg,0.3mmol),H2biim (20.1mg,0.15mmol),NaOH(12.0mg,0.3 mmol),and H2O (10mL)was stirred at room temperature for 15min,and then sealed in a25mL Teflon-lined stainless steel vessel,and heated at 160 1C for 3days,followed by cooling to room temperature at a rate of 10 1C/h. Colorless block-shaped crystals were isolated manually,and washed with distilled water.Yield: 55%(basedon5-BrnicH).CalcdforC24H14Br2ZnN4O4:C 44.51%,H2.18%,N8.65%.Found:C44.17%,H1.84%,N8.24%.IR (KBr,cm1): 1609vs,1552m,1441m,1394w,1370vs,1342w,1281m,1237w,1181w,1125s,1088w,1028m,991w,925w,887w,862w,771m,754m,732m,687m,553w,and434w.
The synthetic route of 1H,1’H-2,2′-Biimidazole has been constantly updated, and we look forward to future research findings.
