- Application of FSO2N3 in preparation of diazo reagent
-
The invention discloses application of FSO2N3 in preparation of a diazo reagent. The application comprises the following step: in the presence of alkali, FSO2N3 and acetone dimethyl phosphate as shown in a formula 2 are subjected to a reaction as shown in the specification, and a Bestmann-Ohira and/or Seyferth-Gilbert reagent is obtained. According to the application, the Seyferth-Gilbert reagent and/or the Bestmann-Ohira reagent can be obtained at a high yield in half an hour, the two mixed reagents generated in the reaction do not need to be separated, and the one-pot method is directly applied to the synthesis of the terminal alkyne compound. And/or like.
