Reactions of Triosmium Carbonyl Clusters with Thionylaniline. Crystal Structures of Os3(CO)9(μ3-NPh)(μ3-S), Os3(CO)9(μ3-η2-(PhN)2SO)(μ3-S), and Os3(CO)8(NCMe)(μ3-NPh)(μ3-S)
Abstract:Reaction of Os(3)(CO)(12) with thionylaniline (PhN=S=O) in refluxing methylcyclohexane produces Os(3)(CO)(9)(&mgr;(3)-NPh)(&mgr;(3)-S) (1) in good yield. When Os(3)(CO)(10)(NCMe)(2) is treated with PhN=S=O at room temperature, compound 1 and Os(3)(CO)(9)(&mgr;(3)-eta(2)-(PhN)(2)SO)(&mgr;(3)-S) (2) result. Compound 1 reacts with trimethylamine oxide in the presence of acetonitrile to give Os(3)(CO)(8)(NCMe)(&mgr;(3)-NPh)(&mgr;(3)-S) (3). Compounds 1-3 were characterized by mass, IR, and NMR spectroscopies, and … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
