A novel [1+1+3] annulation of AgNOx, isocyanides, and isocyanates for the selective synthesis of 1,2,4-triazoles is presented herein. In this transformation, AgNOx and isocyanates are used as nitrogen sources instead of the traditional hydrazine or diazonium reagents. This process also involves N–O/C–H/C═N bond cleavage and the construction of new N–N/C–N bonds with a good substrate scope and functional group tolerance.

AgNOx 作为异氰酸酯与异氰酸酯的 [1+1+3] 环加成反应的氮源：1,2,4-三唑的选择性合成


本文提出了一种用于选择性合成 1,2,4-三唑的 AgNOx、异氰化物和异氰酸酯的新型 [1+1+3] 环化。在此转化中，AgNOx 和异氰酸酯用作氮源，而不是传统的肼或重氮试剂。该过程还涉及 N-O/C-H/C=N 键断裂以及具有良好底物范围和官能团耐受性的新 N-N/C-N 键的构建。
