Abstract

Treatment of 16e complex (p-cymene)Ru(S₂C₂B₁₀H₁₀) (1) with PhCH(OH)C≡CH in CH₂Cl₂ at room temperature leads to two novel complexes (p-cymene)Ru(S₂C₂B₁₀H₉)(PhCH=CCH₂OCH(Ph)C≡CH) (2) and (p-cymene)Ru(S₂C₂B₁₀H₉)(PhCH(OH)C=CH₂) (3). Both complexes have been characterized through elemental analysis, mass, IR and NMR spectroscopies. Notably, complex 2 has been studied by X-ray diffraction. It has been determined that complex 2 crystallizes in triclinic system, space group P \(\overline{1}\) with: a = 11.1020(10) Å, b = 11.8445(10) Å, c = 13.8071(12) Å, α = 78.3630(10)°, β = 75.7330(10)°, γ = 68.7580(10)°, C₃₀H₃₈B₁₀ORuS₂, M_r = 687.89, V = 1627.3(2) ų, ρ = 1.404 g/cm³, Z = 2, F(000) = 704, µ(MoK_α) = 0.636 mm^–1, R = 0.0388 and ωR = 0.1100 for 5658 observed reflections (I > 2σ(I)). The formation mechanisms for the title complexes have been studied.
