    Heck coupling reactions of aryl halides catalyzed by saturated ferrocenylmethylimidazolinium salts/palladium
    (SPRINGER) Musaoglu, D; Ozbek, HA; Demirhan, F
    In situ prepared Pd(OAc)(2)/N,N '-bis(ferrocenyl methyl) imidazolinium salt catalyst systems were successfully applied to Heck reactions of various aryl halides (bromides, iodides) with olefins (styrene, ethyl acrylate). Catalytic studies showed that N,N '-bis(ferrocenylmethyl)imidazolinium chloride containing a saturated imidazole ring as an auxiliary catalyst in the presence of Pd(OAc)(2) was highly efficient in Heck coupling reaction of aryl halides in DMF.
