Synthesis and characterization of a cationic ruthenium complex featuring an unusual bis(eta(2)-BH) monoborane ligand
The reaction of (CpRu)-Ru-star((PPr3)-Pr-i)Cl with MesBH(2) (Mes = 2,4,6-trimethylphenyl), followed by chloride abstraction with LiB(C6F5)(4) center dot 2.5OEt(2) (LiBF20), afforded the crystallographically characterized complex [(CpRu)-Ru-star((PPr3)-Pr-i)(BH(2)Mes)]B+(C6F5)(4)(-); notably, this represents the first reported cationic complex to feature an eta(2)-BH monoborane ligand, as well as a rare example of bis(eta(2)-BH) ligation.
