A novel method to access 1,1-diarylalkanes from readily available, nonactivated alkyl bromides and aryl bromides via visible-light-driven nickel and iridium dual catalysis, wherein diisopropylamine (iPr2NH) is used as the terminal stoichiometric reductant, is reported. Both primary and secondary alkyl bromides can be successfully transformed into the migratory benzylic arylation products with good
报道了一种通过可见光驱动的镍和铱双重催化从现成的未活化烷基溴化物和芳基溴化物中获取1,1-二芳基烷烃的新方法,其中二异丙胺(i Pr 2 NH)被用作末端化学计量还原剂。 。伯烷基溴和仲烷基溴都可以以良好的选择性成功地转化成迁移性苄基芳基化产物。此外,该方法还显示了对多种功能基团的耐受性以及碱基的存在。
