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.

The carbon–nitrogen bond is one of the most prevalent chemical bonds in natural and artificial molecules, as many naturally existing organic molecules, pharmaceuticals, agrochemicals, and functional materials contain at least one nitrogen atom. Radical decarboxylative carbon–nitrogen bond formation from readily available carboxylic acids and their derivatives has emerged as an attractive and valuable tool in modern synthetic chemistry. The promising achievements in this research topic have been demonstrated via utilizing this strategy in the synthesis of complex natural products. In this review, we will cover carbon–nitrogen bond formation via radical decarboxylation of carboxylic acids, Barton esters, MPDOC esters, N–hydroxyphthalimide esters (NHP esters), oxime esters, aryliodine(III) dicarboxylates, and others, respectively. This review aims to bring readers a comprehensive survey of the development in this rapidly expanding field. We hope that this review will emphasize the knowledge, highlight the proposed mechanisms, and further disclose the fascinating features in modern synthetic applications. [ABSTRACT FROM AUTHOR]
