Title:
APPLICATION OF FSO2N3 IN PREPARATION OF AZIDE
Document Type and Number:
WIPO Patent Application WO/2019/238057
Kind Code:
A1
Abstract:
An application of FSO2N3 in preparation of azide. FSO2N3 is used for implementing a diazo transfer reaction, and azide (R-N3, Ar-N3, or RSO2N3) can be quickly and safely prepared from primary amine compounds (comprising a primary alkyl amine compound (R-NH2), a (hetero)aryl amine compound (Ar-NH2), or a sulfonyl amine compound (RSO2NH2)) with a high yield. The operation is simple and highly efficient.
