These common heterocyclic compound, 7189-69-7, name is 1,1′-Sulfonyldiimidazole, 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. Recommanded Product: 7189-69-7
Zn(NO3)26H2O (75 mg, 0.25 mmol), sdi (10 mg, 0.05 mmol) andmalonic acid (52 mg, 0.05 mmol) were mixed in 5 mL of methanol.The pH of the solution was adjusted to 5.0 by the addition of HNO3solution. The mixture was stirred for 30 min at room temperatureand filtered into a glass tube. Colorless crystals of 2 were obtainedin 5 days and collected by filtration, washed with water, and thendried in air. 89% yield (based on sdi). Anal. calcd (%): C, 23.17; H,2.57; N, 22.53. Found (%): C, 23.02; H, 2.64; N, 22.39. IR (KBr, cm1):3447 (m), 3126 (m), 2426 (w), 1637 (m), 1552 (m), 1456 (m), 1384(s), 1206 (m), 1165 (m), 1061 (m), 932 (m), 839 (m), 735 (m), 642(m), 619 (m), 575 (m).
The synthetic route of 1,1′-Sulfonyldiimidazole has been constantly updated, and we look forward to future research findings.
