A visible light-promoted generation of nitrilium ions from diazoacetates and nitriles has been developed. The reaction utilized visible light transformation of diazoacetates to the free carbene that could be trapped by nitriles to generate nitrilium ions, followed by nucleophilic attack on the benzotriazoles and carboxylic acids. This protocol provides an efficient and practical approach to N-imidoylbenzotriazoles and diacylglycine esters in good to excellent yields.

可见光促进的重氮乙酸盐和腈产生被苯并三唑和羧酸捕获的腈离子

已经开发出一种可见光促进的从重氮乙酸盐和腈中产生腈离子的方法。该反应利用重氮乙酸盐的可见光转化为游离卡宾，该游离卡宾可以被腈捕获以产生腈离子，然后对苯并三唑和羧酸进行亲核攻击。该协议为N -imidoylbenzotriazoles 和 diacylglycine 酯提供了一种有效且实用的方法，收率良好。
