A novel and convenient synthesis of E,E-bis(styryl)sulfones and E,E-1,4-diaryl-1,3-butadienes

The condensation of 2-phenylethanesulfonylacetic acid (4) with araldehydes (5) in presence of a base gave E-styryl-2-phenylethyl sulfones (6) which on dehydrogenation with DDQ (7) yielded E,E-bis-(styryl)sulfones (8). The 8 on treatment with dichlorotris(triphenyl-phosphine)ruthehium(II) catalyst resulted 1,4-diaryl-1,3-butadienes (9). The configurations of 6, 8 and 9 have been determined based on IR and 1H NMR spectral data.
