The synthesis and X-ray structures of three new [Cp*Ru(η¹-ArCN)₃]PF₆ (Ar = aryl) complexes are reported. These complexes are thermally converted to [Cp*Ru(η⁶-ArCN)]PF₆ (Ar = aryl) sandwich complexes and subsequently recovered by UV light irradiation. The structures of the sandwich complexes are likewise determined. Trans-selective hydroboration of internal alkynes using the synthesized complexes is disclosed.
