Chlorodifluoromethyl ketones compounds

Chlorodifluoromethyl Ketone Metal Carbonyl Compound Yield of Aldol (%)... 

Various chlorodifluoromethyl p-substituted aryl ketones and sulfones have been evaluated for their potential as CF2 carbene sources for N- and 0-difluoromethylations of V-heterocyclic compounds and phenols.Electron-poor sulfones, especially p-chloro- and p-nitro-substituted sulfones, proved to be the most powerful O-difluoromethylating agents, the corresponding difluoromethylated phenols being obtained in good to excellent yields.
