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
3-Fluorobutenone (7) reacts with aryl triazenes in the presence of zinc iodide to give 4-aryl-3-fluoro-3-iodo-2-butanones (9a–9f) in moderate yields. The products arise from a free radical process that terminated by iodination of an alkyl radical. The process yields unusual geminal iodo-fluoro compounds.
