The reactions of allylic or benzylic bromides with 1-alkenyldisiamylboranes readily available from 1-alkynes in the presence of sodium hydroxide and catalytic amounts of tetrakis-(triphenylphosphine)palladium to give corresponding 1,4-alkadienes or allylbenzenes in good yields.
在氢氧化钠和催化量的四-(三苯基膦)钯的存在下,烯丙基或苄基溴化物与1-烯基二氮杂戊二烯易于从1-炔烃中反应,以高收率得到相应的1,4-链二烯或烯丙基苯。
