Magnesium.— The exchange route to perfluoroalkylmagnesium halides, RfX + RMgBr RpMgBr + RX (X = Br or I R = alkyl or aryl), has received attention by two groups, one of which has presented - in detail its conclusions regarding the effects of reaction variables on yields (see Schemes 3 and 4 - for... 

Among the first useful synthetic application that made use of a halogen-magnesium exchange reaction was the preparation of perfluoroalkylmagnesium halides such as 21 starting from the corresponding perfluorinated iodides such as 22. The...
