【Abstract】 The generally accepted mechanisms for the Grignard reactions of ketones are des-cribed.Evidences supporting the single electron transfer(SET)process in some of the reac-tions under certain conditions are presented.some main factors,including structure of reac-tants,nature of solvents and effect of transition-metal impurities,which might affect thecourse and mechanism(ionic or/and SET)of the reactions are also discussed.更多还原
