A NOVEL SYNTHESIS OF (E,E)-1,4-DIARYL-1,3-BUTADIENES BY THE RUTHENIUM(II) CATALYZED REACTION OF (E)-2-ARYLETHENESULFONYL CHLORIDES WITH VINYLARENES

Article abstract of DOI:10.1246/cl.1985.705

Symmetrical and unsymmetrical (E,E)-1,4-diaryl-1,3-butadienes can be prepared in high yields from (E)-2-arylethenesulfonyl chlorides by treating with vinylarenes in the presence of ruthenium(II) phosphine complex in benzene.
