Addition reactions of the fluorinated acyl hypochlorites CF3CO2C1, C $ F6C02C1, n- C3F7C02C1, ClCF2C02Cl, and HCF2C02Cl with CF2= CF2 and CF2= CH2 form the respective esters in varying yields. The reactions are regiospecific with CF2= CH2. Additional reactions of CF3C02Cl with CF2= CFCl, CF2= CC12, CH2= CH2, and cis-and trans-CFH= CFH further illustrate the potential of the acyl hypochlorites for the synthesis of ...
