Literature References

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 ɑß-unsaturated ester: J. Fluorine Chem., 89, 141 (1998):
