Several new polyfluoroalkyl hypochlorites and fluoroxy compounds containing Cl, H andBr in the alkyl group have been prepared and characterized by 19F NMR, 1H NMR andIR spectroscopies and by their reactions with fluoroalkenes to produce new polyfluoroethers.The novel compounds are prepared by the CsF-catalyzed addition of F2 or ClF to theCO bond in CF3C(O)CF2Cl, ClCF2C(O)CF2Cl, and their derivatives

An extension of the scope of the Grignardreaction of fluorinated compounds is reported. Fluorohalogenoethanes of the general formula CF3CXYZ ( X = F,Cl,Br ; Y,Z = Cl,Br ) were found to undergo smoothly the metal-halogen exchange reaction with alkyl- or aryl-magnesium halides at low temperature to yield organometallic compounds CF3CXYMgHal. The Grignard compounds were reacted with a series of aldehydes
