摘要: The reaction of 1-hydroxypyridine-2-thione with Os3(CO)11(NCMe) has yielded three new complexes Os3(CO)10(μ-H)(μ-η1-S-C5H4N(O)) (1, 11% yield), Os3(CO)10(μ-H)(η2-S-C5H4N(O)) (2, 16% and Os3(CO)9(μ-H)(μ-η2:η1-SC5H4N(O)) (3, 3% yield). Similarly, treatment complex Os3(CO)10(NCMe)2 this ligand produced the major 1 trace 3. Prolonging above two reactions increased yield Treatment triosmium isocyanide Os3(CO)10(CNR)(NCMe) (a, R = CH2Ph; b, Pr) led to formation Os3(CO)9(μ-H)(CNR)(η2-SC5H4N(O)) (4), Os3(CO)10(μ-η1-CNHCH2Ph)(μ-η1-S-C5H4N(O)) (5), Os3(CO)9(μ-H)(CNR)(μ-η1-S-C5H4N(O)) (6). 4:5 ratio depended upon nature alkyl groups coordinated isocyanide. Reaction either or 2 Me3NO resulted in CO loss Thermolysis at 80 °C generated Os3(CO)9(μ-H)(μ3-pyS) (7), Os3(CO)9(μ-OH)(μ3-pyS) (8), byproduct CO2. Upon being heated °C, 3 was ...
