An electron‐rich monovalent boron compound is used as a Lewis base to prepare adducts with Group 13 Lewis acids using both its boron and nitrogen sites. The hard Lewis acid AlCl 3 binds through a nitrogen atom of the Lewis base, while softer Lewis acids GaX 3 (Cl, Br, I) bind at the boron atom. The latter are the first noncluster Lewis adducts between a boron‐centered Lewis base and a main‐group Lewis acid.
