✦ Synopsis

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