Tetrakis(triphenylphosphine)platinum in DMF was utilized as a mild catalyst for cross-coupling reactions of organoboronicacids with aryliodides. The present reactions exhibited excellent group-selectivity where couplings of organoboronicacids 2a–e with 4-bromo-1-iodobenzene (4) give 4-arylbromobenzenes 5a–b and 4-alkenylbromobenzenes 5c–e in excellent yields.

Oligoarylenes with three or four aromatic rings, bearing two S-acetylated mercaptomethyl groups in 1,3 position on one end of the polyaromatic system and presenting various functionalities on the other terminal ring, have been synthesized by the Suzuki−Miyaura cross-coupling reaction. The use of palladium complexes with a Buchwald's phosphine as ligand allowed us to perform this coupling reaction also
