means of an iodine-catalyzed direct indium insertion into alkyl iodide in THF is reported. The thus-generated alkyl indium reagents effectively underwent Pd-catalyzed cross-coupling reactions with various aryl halides, exhibiting good compatibility to a variety of sensitive functional groups. By replacing THF with DMA and using 0.75 equiv of iodine, less reactive alkyl bromide could be used as substrate
报道了一种通过碘催化的将铟直接插入到THF中的烷基碘中来合成烷基铟试剂的有效方法。如此生成的烷基铟试剂可有效地与各种芳基卤化物进行Pd催化的交叉偶联反应,表现出与各种敏感官能团的良好相容性。通过用DMA代替THF并使用0.75当量的碘,同等容易程度的反应性较低的烷基溴可以用作铟插入的底物。
