Title cumulenes 2a and 2b were prepared by reaction of CF3(Ph)C=C(Br)ZnX 1 with CuBr, or by oxidative coupling of 1 with FeCl3 to form 2a,b and 2 3, which can be dehalogenated with zinc to afford 2a,b; the cumulene isomers are readily separated by silica-gel chromatography, and may be prepared in good yield on a multi-gram scale.
