Displacement of both chloro groups from the dichloroboryl ligand of 1 by reaction with 8‐aminoquinoline gives the internally base‐stabilized terminal borylene complex 2 . The electrophilic boron center in this complex is attacked by ethanol to form the ethoxyboryl complex [█Os{B(OEt)NHC 9 H 6 █N}Cl(CO)(PPh 3 ) 2 ] in which the quinoline N atom is tethered to the coordinated Os center.
