Zinc(II) promoted conversion of aryltriazenes to aryl iodides and aryl nitriles
摘要:
Aryltriazenes react with zinc perchlorate/zinc cyanide to produces arylnitriles and react with zinc iodide to produce aryliodides. The reaction mechanism involves aryl radicals that have been trapped by addition to propenenitriles in a good preparative Meerwein arylation process. (C) 2001 Elsevier Science Ltd.

range of diazonium salts and their corresponding triazenes have been prepared in order to directly compare their relative thermal stabilities (via initial decomposition temperature) from differential scanning calorimetry (DSC) data. A structure–stability relationship has been explored to investigate trends in stability, depending on the aromatic substituent and the structure of the secondary amine component

Functionalized lactams are an important class of heterocycles since they are useful intermediates in organic synthesis and show biological activity in diverse therapeutic applications. In the herein presented study, a strategy for the synthesis of N-aryldiazenyllactams, offering the direct access to protected lactamderivatives is described. After the formation of triazenes from diazonium salts and
