The title compound was synthesized from a trifluoroisopropenyl-zinc reagent and E-(2-bromoethenyl)di-isopropoxyborane. As a potentially useful building block for trifluoromethylated compounds, this trifluoromethyl-containing boron reagent underwent a palladium-catalyzed stereospecific coupling reaction with aryl halides to afford E-1-aryl-3-trifluoromethyl-1,3-butadienes.
