Melted poly(ethylene glycol)s (PEG)s were used for the first time as solvent for the sonochemical cyanation of aryl halides using K4[Fe(CN)6] and a relative low amount of Cu catalyst (5%). The weight-average molecular weight of PEG was proven to exert a notable influence on conversion, and CuI proved to be the most efficient catalyst, affording good results within short reaction times with the use of aryl iodides and activated aryl bromides as substrates

Abstract
Melted poly(ethylene glycol)s (PEG)s were used for the first time as solvent for the sonochemical cyanation of aryl halides using K4[Fe(CN)6] and a relative low amount of Cu catalyst (5%). The weight-average molecular weight of PEG was proven to exert a notable influence on conversion, and CuI proved to be the most efficient catalyst, affording good results within short reaction times with the use of aryl iodides and activated aryl bromides as substratesFile in questo prodotto:
