• Wadsworth-Emmons precursor of methacrylic esters (see Triethyl phosphonoacetate, A14120 and Appendix 1). Lithiation followed by acylation with perfluoroalkanoic anhydrides gives a perfluoroacyl intermediate which, with an organolithium reagent, leads stereoselectively to a trifluoroalkylated ɑ?-unsaturated ester: J.
