Synthesis of Carbamoyl Azides from Redox-Active Esters and TMSN3.

This article explores a new method for synthesizing carbamoyl azides, which are important for creating amines. The authors propose using NHP esters and TMSN3 to form C-N bonds through a nucleophilic substitution process. They optimized the reaction conditions and demonstrated the method's effectiveness with various NHP esters. Control experiments were conducted to understand the mechanism, which involves the coordination of NHP esters with ferric acetate, nucleophilic attack, and Curtius rearrangement. This method offers a convenient and efficient approach for synthesizing carbamoyl azides. The authors of the article are Xiaobin Yuan, Yanjie Qu, Yajun Li, and Hongli Bao. [Extracted from the article]
