| Use | for the preparation of diazomethane. it can be used for the production of diazomethane, and its properties are obviously better than other nitroso compounds used for the preparation of diazomethane it can be used for the production of diazomethane, its properties are significantly better than other nitroso compounds used to prepare diazomethane |
| production method | N-methyl-p-toluenesulfonamide was dissolved in glacial acetic acid, cooled to 5 ℃, sodium nitrite aqueous solution was added dropwise, the reaction precipitated N-methyl-N-nitroso-p-toluenesulfonamide as yellow. N-methyl-p-toluenesulfonamide is obtained from the reaction of p-Toluenesulfonyl chloride with methylamine. |
