Controlled abstraction : [Ph 3 C][B(C 6 F 5 ) 4 ] is best known for its excellent ability to abstract alkyl ligands, however, the present study on mono(indenyl)–Sc–dialkyl/[Ph 3 C][B(C 6 F 5 ) 4 ] systems has found that [Ph 3 C][B(C 6 F 5 ) 4 ] can abstract a π‐bonded indenyl ligand rather than a σ‐alkyl ligand (see scheme). The abstraction pathway can be controlled by changing the substituents on the indenyl ligands.
