procedure for the direct preparation of triorganoindium reagents from organic halides by means of magnesium insertion in the presence of InCl3 and LiCl is reported (see scheme). The organoindium reagents are obtained in good yields from functionalized aryl, heteroaryl, and alkyl bromides and benzyl chlorides at 25 °C in THF within 4 h. Moreover, the resulting organoindium reagents could be efficiently
镁,铟,钯:报道了一种有效的单锅法,该方法可在InCl 3和LiCl存在下通过插入镁从有机卤化物直接制备三有机铟试剂(参见方案)。在25℃,4小时内于THF中从官能化的芳基,杂芳基和烷基溴化物和苄基氯获得高产率的有机铟试剂。此外,所得的有机铟试剂可有效地用作Pd催化的交叉偶联反应中的试剂,且具有宽泛的官能团耐受性。
