摘要：

[{(eta(6)-p-cymene)OsCl(mu-Cl)}(2)] reacts with silver triflate and thiophenes to give the sandwich compounds [Os(eta(6)-p-cymene)(eta(5-)thio)](OTf)(2) (thio = thiophene, 2,5-dimethylthiophene (DMT), 2,3,4,5-tetramethylthiophene (TMT)). While these compounds do not react cleanly with nucleophiles to form thiopheneyl derivatives, they do react via base hydrolysis to give new acyl thiolate complexes, [Os(eta(6)-p-cymene)(SC(3)R(3)C(O)R)], which have closely related ruthenium analogues.
