IBzH (IBenzhydryl): Sterically-Flexible N-Aliphatic N-Heterocyclic Carbenes (NHC) for Iron-Catalyzed C(sp3)–C(sp2) Cross-Coupling of Unactivated Haloalkanes

We present IBzH, a benzhydryl-substituted N -heterocyclic carbene that facilitates challenging C(sp 3 )–C(sp 2 ) iron-catalyzed cross-coupling of unactivated haloalkanes and shows potential for broad applications due to its steric flexibility.
