4-Methoxy-1-oxidopyridin-1-ium - Reference Information
| NIST chemical information | Information provided by: webbook.nist.gov (external link) |
| application | N-oxides are generally obtained by the oxidation of corresponding tertiary amines. they are an important organic chemical intermediates and are widely used in organic synthesis (as oxidants, reaction intermediates, and structural units of a variety of important biologically active substances. |
| preparation | add 4mL of methanol, then add 4-methoxypyridine (0.5mmol,54.6mg), then add 30% H2O2(6.0eq.,0.3mL), potassium carbonate (4.0eq.,276.4mg) into a 25 ml round bottom two-mouth bottle, and use two straight piston straight bending joints at the same time, while connecting the balloon with a hose, SO2F2 gas is introduced, and the reaction is stirred at room temperature of 23~32 ℃ for 20~40min under sealing conditions. After the reaction, filter to remove the potassium carbonate solid, dry with anhydrous sodium sulfate to remove water and filter again, concentrate the solvent to obtain the crude product, and finally undergo column chromatography separation and purification to obtain 4-methoxypyridine nitrogen oxide 40.3mg, The yield is 65.4%. |
