Cyclic perfluoroketones

Aromatic aldehydes and cyclic perfluoroketones are oxidized to a-hydroxy hydroperoxides or bis(a-hydroxy) peroxides, aliphatic ketones are converted to esters, and ketenes are converted to a-lactones... 

Ketones and aldehydes insert into B-X bonds, and the products vary with the substituents on the substrateU Thus, with BX3 either mono-, bis-, or tn s-inserted products may be obtained in which B-0 bonds are formed. Electron-withdrawing substituents favor insertion. Reactions with ketenes lead to insertion into both the C=C and C=0 bonds . 1,3-Addition of PhBCU occurs with a-diazoethylacetates to form PhClBOC(OEt)=CRCl under mild conditions. Cyclic perfluoroketones react with... 

Acyclic [87, 88], cyclic, cage [89-91] and poly [91, 92]-perfluoroketones have been successfully synthesised by direct perfluorination (Figs. 29 and 30).
