The Reformatsky reagent, prepared from the title bromo-ester and zinc powder in dioxane, is found to be thermally stable enough to undergo addition reactions with aldehydes to afford the α-trifluoromethyl-β-hydroxy esters in high yields. The unique reactivity of the fluorinated zinc reagent is discussed.
