Carbon-chlonne bond

Acyl cations form by coordination of an acyl chloride with aluminum chloride followed by cleavage of the carbon-chlonne bond... 

The carbon-fluonne bond is normally resistant to cleavage by zinc metal so that the carbon-chlonne bond in chlorodifluoromethyl ketones is selecnvely reduced The... 

Reductive cleavages of carbon-chlonne bonds by active metals and with photochemical activation figure in recent studies aimed at HFCs and HCFCs Sodium amalgam [33] (equation 25), zinc powder [34] (equation 26), and alumi-num/tin chloride [35] (equation 26) are all used in conjunction with protic solvents in reactions giving high yields and conversions... 

Copyrolysis of 1,1-diehloroperfluoroindane and chlorodifluoromethane or tetrafluoroethylene gives 1-perfluoromethyleneindane as the major product and three minor products [3] (equation 2) Insertion of difluorocatbene into the benzylic carbon-chlorine bond and subsequent loss of a chlonne molecule is observed in the copyrolysis of chlorodifluoromethane and pentafluorobenzotnchlonde to give a-chloroperfluorostyrene as the major product. Aromatic carbon-chlorine bonds are unreactive to the difluorocarbene in this reaction [4] (equation 3). 

The last example represents a fairly rate eliminatum of hydrogen fluoride in preference to hydrogen chloride, a reaction that deserves a more detailed discussion A comparison of bond dissociation energies of carbon-halogen bonds shows that the carbon-fluorine bond is much stronger than the caibon-chlonne, carbon-bromine, and carbon-iodine bonds 108-116, 83 5, 70, and 56 kcal/mol, respec-...
