[RuCl2(κP-η6-phenyl)-P(2-biphenylyl)PhR] complex (9c), where the coordinated phenyl ring belongs to the 2-biphenylyl group. Reaction of P(2-biphenylyl)PhR (R = OMe, Me, i-Pr, and Fc (ferrocenyl)) with Dim2 has given complexes [RuCl2(η6-methyl benzoate)(κP-P(2-biphenylyl)PhR)] (10c–13c). The replacement of methyl benzoate by the phenyl ring of the 2-biphenylyl of the phosphine can be performed at room temperature
