Catalyzed by ligand free Pd(OAc)2, 2,5-disubstituted imidazole was prepared in good yield by the reaction of fluorinated propargyl amidines with iodoarene. Mechanistic studies indicated that this transformation occurs through a nitropalladation–reductive elimination pathway.
在无配体钯(OAc)2 的催化下,氟化丙炔脒与碘代烯烃反应制备出了 2,5-二取代咪唑,收率很高。机理研究表明,这种转化是通过硝基钯化还原消除途径进行的。
