One thing leads to another : Reactions of the cationic BN vinylidene analogues 1 ‐[BAr F 4 ] (R=Cy, i Pr; Ar F =3,5‐(CF 3 ) 2 C 6 H 3 ) towards dicyclohexylcarbodiimide proceed by unprecedented insertion chemistry for terminal borylene complexes. Controlled, stepwise insertion into the FeB and BN bonds is demonstrated, sequentially forming four‐membered rings linked at a spirocyclic boronium center.
