interested in the straightforward method for the synthesis of 1,1-difluoro- 1,3-butadienes from the cross-coupling reaction of 2,2-diflu-oroalkenylmetal reagent with alkenyl halides, which should be a simple and efficient method. Palladium-catalyzed cross- coupling reactions of 1,1-difluorohomoallenyl bromide with aryl bromides and iodides and aryl boronic acids provided the corresponding 1,1-difluoro-1,3-butadienes
然而,我们对通过 2,2-二氟-口烯基金属试剂与烯基卤化物的交叉偶联反应合成 1,1-二氟-1,3-丁二烯的直接方法感兴趣,这应该是一种简单有效的方法。方法。1,1-二氟高烯丙基溴与芳基溴化物和碘化物以及芳基硼酸的钯催化交叉偶联反应提供了相应的1,1-二氟-1,3-丁二烯。
