摘要：

A highly effective method for derivatizing 2,1-borazaronaphthalene cores using ammonium alkylbis-(catecholato)silicates via photoredox/nickel dual catalysis is reported. By forging C-sp(3)-C-sp(2) bonds via this approach, alkyl fragments with various functional groups can be introduced to the azaborine core, affording previously inaccessible heterocyclic isosteres in good to excellent yields. The base-free, room-temperature conditions outlined allow sensitive functional group tolerance, even permitting the cross-coupling of unprotected primary and secondary amines.
