title: (E)-1,2-Diphenyl-vinyl p-toluene-sulfonate.
abstract: The title compound, C(21)H(18)O(3)S, is the E isomer, the ester -oxy link being trans to one of the phenyl groups. The planes of the phenyl substituents at the vinyl C atoms form a dihedral angle of 66.32 (7)° with each other. The vinyl group shows noticeable non-planarity, the C(Ph)-C=C-C(Ph) torsion angle being 8.4 (3)°.
