title = "Chemistry of bis(2-ethynyl-3-thienyl)arene and related systems, part 5: Preparation of an unsymmetrical 4,4′-bis(3-thienyl)biphenyl derivative containing a 2-[2-(diphenylphosphino)ethynyl]-3-thienyl moiety",
abstract = "An unsymmetrically substituted 4,4′-bis(3-thienyl)biphenyl derivative of 4-(2-ethynyl-3-thienyl)-4′-(3-thienyl)biphenyl type was prepared, utilizing 4-bromo-4′-(2-iodo-3-thienyl) biphenyl as synthetic intermediate. Reaction of 4-(2-ethynyl-3-thienyl)-4′-(3-thienyl) biphenyl with ethylmagnesium bromide followed by treatment with chlorodiphenylphosphine afforded 4-[2-(2-diphenylphosphinoethynyl)-3-thienyl]-4′-(3-thienyl) biphenyl.",
