Darstellung und Charakterisierung von Wolframkomplexen mit ER−-Liganden; E = O,S, Se,Te; R = Alkyl,Aryl

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.
