Halides carbonyl difluoride

Dichlorodifluoromethane reacts with WO at 525 C mainly to give CO, WOF and WOCl. Small amounts of phosgene and carbonyl difluoride are also formed, but these compounds may arise from the reactions of the CO with the nickel halide films formed on the inside surfaces of the nickel reactor [2159]. 

Thus, treatment of phosgene with an excess of SOFj at 400 "C (in the presence of a metal halide catalyst, such as FeClj, AICI3, UCl, LaFj, WOF or SbCl ) gives carbonyl difluoride in 96% conversion based upon phosgene [704],... 

The CAS Registry numbers for the carbonyl halides, and their principal isotopomers, are given in Table A3.1. Synonyms and foreign language equivalents for phosgene are given in Table A3.2, and for carbonyl difluoride in Table A3.3. 

The addition to the C=N bond is limited to reactive species, such as hydrogen halides, carbonyl fluoride and organometallics, and seems to proceed well only with carbonimidoyl difluorides. The dehalogenation of carbonimidoyl dihalides by triphenylphosphine provides a useful method to generate isocyanides, which are sometimes difficult to obtain by Hofmann s classical method.
