摘要

Abstract We have developed the diazo-transfer of 2-azido-1, 3-dimethylimidazolinium salts to 1, 3-dicarbonyl compounds. 2-Azido-1, 3-dimethylimidazolinium chloride (ADMC) was prepared by N-nitrosation of N-aminoguanidine or by the reaction of 2-chloro-1, 3- dimethylimidazolinium chloride (DMC) and sodium azide. The corresponding phosphate, ADMP, was isolated as a crystal, and was found to be a stable and safe reagent. Both ...
