| titleOfInvention | Preparation method of ortho-trifluoromethyl substituted azide |
| abstract | The invention relates to a preparation method of an ortho-trifluoromethyl substituted azide. The method comprises the following steps: adding manganese salt, olefin derivatives, sodium trifluoromethanesulfonate, trimethylsilyl azide and peroxy compounds into a solvent under the atmosphere of inert gas, reacting for 6-12 hours at the temperature of 25-75 ℃, and separating and purifying by column chromatography to obtain ortho-trifluoromethyl-substituted azide; wherein, the molar ratio of manganese salt: olefin derivatives: sodium trifluoromethanesulfonate: azidotrimethylsilane: peroxy compound 0.1-0.2: 1: 1.5-2.5: 2.5-3.5: 2.5-3.5; the amount of the solvent is 6-7 ml per millimole of the olefin derivative. The invention has the advantages of low raw material price, mild reaction condition and simple post-treatment, and is suitable for industrial production. |
