摘要: Abstract The reactions of the electron deficient cluster [(μ-H)Os3(CO)9μ3-η2-C9H5(CH3)N] 5 with C2H5SH, C6H5SH and H2S are reported. reaction RSH at 25°C affords dihydrido clusters [H(μ-H)Os3(CO)9μ-η2-C9H5(CH3)N(μ-SR)] (R=C2H5 6, R = C6H5 7) in which hydrides exhibit dynamic behaviour on NMR timescale while yields known S-capped dihydridro [(μ-H)2Os3(CO)9(μ3-S)] 8. 6 is thermally decarbonylated to give [(μ-H)2Os3(CO)8μ-η2-C9H5(CH3)N(μ-SC2H5)] 9, [(μ-H)Os3(CO)10(μ-SC2H5)] 10 Compounds 7 react CCl4 77°C [Os3(CO)8Cl2μ-η2-C9H5(CH3)N(μ-SR)] (R C2H5 11, 12). All compounds have been characterized by 1H NMR, infrared spectroscopy elemental analysis. Compound has also X-ray crystallography.
