ALPHA-ACYLATION AND -ALLYLATION OF β,β,β-TRIFLUOROPROPIONIC ESTERS VIA THE KETENE SILYL ACETALS

Article abstract of DOI:10.1016/0040-4039(84)80048-9

α-Acylation of the ketene silyl acetal of methyl β,β,β-trifluoropropionate and α-allylation via the ester enolate Claisen rearrangement of the 2-alkenyl trifluoropropionates are described which provide the corresponding α-CF3 β-ketoesters and α-CF3 γ,δ-unsaturated acids, respectively.
