Abstract: | Synthesis and Characterization of Tungsten Complexes with ER?-Ligands, E = O, S, Se, Te; R = Alkyl, Aryl The reaction of η7-C7H7W(CO)2I with ER? bases yielded several types of compounds, η7-C7H7W(CO)2ER, η3-C7H7(CO)2W(μ-OR)3W(CO)2-η4-C7H8, (CO)4W(μ-ER)2W(CO)4, η7-C7H7W(μ-ER)3W(CO)3 and η7-C7H7W(μ-ER)3W(CO)(μ-ER)2W(CO)4. The compounds were characterized by elementary analysis and their spectroscopie data. The structures of typical representatives of every class of compounds were confirmed by X-ray structure analysis. |
