title: (1E,3E,5E)-1,2,3,4,5,6-Hexafluoro-1,6-diphenylhexatriene
abstract: The title triene, C(18)H(10)F(6), was prepared via the Pd(0) coupling reaction of (E)-(1,2-difluoro-1, 2-ethenediyl)bis(tributylstannane) with (Z)-beta-iodo-alpha, beta-difluorostyrene in N,N'-dimethylformamide/tetrahydrofuran. The crystal structure shows the product to be the 1E,3E,5E isomer. Due to steric interactions between F atoms, the double bonds are not coplanar. The planes defined by the two terminal double bonds are almost perpendicular.
