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.
