| titleOfInvention | Method for synthesizing N-methylsulfonamide in water |
| abstract | The invention discloses a method for synthesizing N-methyl sulfonamide in water, which takes sulfonamide and methanol as raw materials and adopts a transition metal iridium catalyst to catalyze N-methylation reaction. The invention uses non-toxic and harmless water as a solvent, and avoids using organic reagents; only water is generated as a byproduct in the reaction, and no environmental hazard is caused; the reaction temperature was milder relative to the previous bars; only the single methylation product is generated in the reaction, and the selectivity is good; the reaction atom has high economy and wide application prospect. |
