Catalytic chlorofluorination of fluoroacyl fluorides: hypochlorites synthesis

A new procedure fo synthetizing the hypochlorittes CF3CF2OCl, CF2BrCF2OCl, and CF2HCF2OCl is reported. In the proposed method hypochlorites can be produced by a continous addition of chlorine monofluoiride (ClF) to an appropriate carbonyl compound.
