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.
DMF中的四(三苯基膦)铂用作有机硼酸与芳基碘化物的交叉偶联反应的温和催化剂。本反应显示出优异的基团选择性,其中有机硼酸2a – e与4-溴-1-碘苯(4)的偶联以优异的收率得到了4-芳基溴苯5a – b和4-烯基溴苯5c – e。
