The synthetic and reaction chemistry of the asymmetric aryl(bromo)boryl complexes (η 5 ‐C 5 H 5 )Fe(CO) 2 B(Ar)Br [Ar = 2,4,6‐Me 3 C 6 H 2 , Mes (3); 2,6‐(2,4,6‐ i Pr 3 C 6 H 2 )C 6 H 3 , 2,6‐Trip 2 C 6 H 3 (4)] are reported. In particular, the scope for substitution at boron by main‐group nucleophiles is probed. The synthesis and characterization of (η 5 ‐C 5 H 5 )Fe(CO) 2 B(Mes)ER n [ER n = O t Bu, (5); ER n = SPh (6)] confirm that substitution at boron can be accomplished with retention of the FeB bond.
