A nickel-catalyzed three-component carboamination of the biphenylene C–C σ-bond has been developed. Arylboronates and hydroxylamine derivatives work as carbon nucleophiles and nitrogen electrophiles, respectively, and the corresponding difunctionalized ring-opening products are obtained in good yields. The arylboronate nucleophile can be replaced with B₂pin₂ (boron nucleophile) and H–Si(OMe)₃ (hydride nucleophile), thus allowing for the aminoboration and hydroamination of the biphenylene C–C σ-bond under similar nickel catalysis.

镍催化亚联苯 C-C σ-键的亲电胺化


已开发出镍催化的联亚苯基 C-C σ 键三组分碳胺化反应。芳基硼酸酯和羟胺衍生物分别作为碳亲核试剂和氮亲电子试剂，并以良好的收率获得了相应的双官能化开环产物。芳基硼酸酯亲核试剂可以用 B ₂ pin ₂ （硼亲核试剂）和 H–Si(OMe) ₃ （氢化物亲核试剂）取代，从而允许在类似的镍催化下，联苯撑C-C σ-键的氨基硼化和氢氨化。
