complexes formed from nickelcarbonyl and F-ketones in donor solvents are stable at 25 °C and decompose on heating with little or no elimination of fluoride ion. However, treatment of one such complex with iodobenzene at 25 °C resulted in benzoylation at oxygen with a concomitant loss of fluoride. Fluoroketones bearing an α-chlorine atom, on the other hand, reacted with nickelcarbonyl at moderate temperatures

Methyl trifluoropyruvate (1) enters into reductive dimerization during UV irradiation in the presence of isopropyl alcohol or of a sensitizer and during reaction with sodium in the presence of trimethyldichlorosilane, giving dimethyl 2,3-bis(trifluoromethyl)-2,3-dihydroxysuccinate. Unlike hexafluoroacetone, compound 1 does not form the reductive dimerization product after prolonged standing over sodium but is converted into the cyclic dimer 2-methoxycarbonyl-4-methoxy-2,4-bis(trifluoromethyl)-1,3-dioxolan-5-one.

A novel trifluoromethyl ketene silyl acetal (4) of methyl trifluoropyruvate (1) was prepared in 82% yield by metal Mg reduction in a (TMS)Cl/THF system. Subsequent carbon−carbon bond formation such as Mukaiyama aldol, Michael addition, and other nucleophilic reactions of 4 at the trifluoromethylated carbon with various electrophiles gave various coupling products in high yields.
