Wadsworth-Emmons (Horner) reaction with aldehydes and ketones gives acrylic esters. See, e.g.: Org. Synth. Coll., 5, 509, 547 (1973), and Appendix 1.
Base-catalyzed aldol, Cannizzaro and saponification reactions can be minimized, by the use of, e.g.: K₂CO₃: Synthesis, 300 (1983); Tetrahedron Lett., 26, 53 (1985); F^-: Tetrahedron Lett., 21, 2161 (1980); N-ethyldiisopropylamine + LiCl: Tetrahedron Lett., 25, 2183 (1984); Et₃N + Li halides: J.

Reaction with aqueous formaldehyde does not lead to the expected Wadsworth-Emmons product, but to ethyl ɑ-(hydroxymethyl)acrylate, a precursor of the synthetically useful ethyl ɑ-bromomethylacrylate, by condensation with the initially-formed aldol product: Org. Synth. Coll., 8, 265 (1993).
