An efficient strategy for the nickel-catalysed synthesis of biaryls and terphenyls has been developed in environmentally-friendly reaction media. In the presence of β-diketone and PPh3 ligands, Ni(TFA)2 acted as an effective catalyst for the Suzuki-Miyaura cross-coupling of aryl halides and arylboronic acids in an ionic liquid solution. Biaryls and terphenyls were obtained in good yields under this catalytic system.
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

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.

Iodination of 1,4-di(3-thienyl)benzene gave 1,4-bis(2-iodo-3-thienyi)-benzene, which was converted to 1,4-bis(2-ethynyl-3-thienyl)benzene. Novel 1,4-bis|2-(pyridylethynyl)-3-thienyl)benzene ligands containing the bis(ethynylthienyl)benzene spacer were pre
