Name is 1,3-Dimethyl-1H-benzo[d]imidazol-3-ium iodide, as a common heterocyclic compound, it belongs to chiral-catalyst compound, and cas is 7181-87-5, its synthesis route is as follows.,7181-87-5
General procedure: General Method: To a 20 mL solution of 1.1 equivalents of nickelocene (41 mg, 0.22 mmol) in anhydrous THF, the respective imidazolium NHC precursor (0.2 mmol) was added as a solid. The resulting suspension was then refluxed for 4 h. The general method was modified for 4, 5 and 6. The reactions involving the formation of more electron-deficient 4 and 5 required 10 h at reflux with 2 equivalents of nickelocene (75 mg, 0.4 mmol). Synthesis of 6 was achieved after 16 h of reflux in the presence of 2.6 equivalents of nickelocene (98 mg, 0.52 mmol). The compounds were then purified by column chromatography. Details available in the Supporting information.
With the complex challenges of chemical substances, we look forward to future research findings about 1,3-Dimethyl-1H-benzo[d]imidazol-3-ium iodide
