cze Systematic metoda inkorporaci {(eta(6)-Arene)Fe} fragmentu do carboranů cestou [(eta(6)-Arene)Fe](2+) dicationtu. Serie [3-(eta(6)-Arene)-closo-3,1,2-FeC2B9H11] komplexů. Syntéya polymethylovaných [(eta(6)-Arenů) Byla vyvinuta systematická metoda pro začlenění {rene)Fe} tragmentu do carboranové klece. Reakce mezi [rene)(2)Fe](PF6)(2) solí a Tl - 2[nido -7,8-C2B9H11] za refluxu v (CH2)(2)Cl-2 poskytla sérii [3 --arene)-closo-3,1,2-FeC2B9H11] neutrálních komplexů s různými typy polymetylovaných arenových ligandů ve struktuře. Struktury z durenových a hexamethylbenzenových komplexů byly ustanovené rentgenovou difrakcí. Práce také ukázala že originál vysokoteplotní metoda pro přípravu [rene)(2)Fe](2+) selhala pro mesitylenové a durenové sloučeniny karbollidy;železo
eng Systematic Method for the Incorporation of the {(eta(6)-Arene)Fe} Fragment into Carborane Cages via [(eta(6)-Arene)Fe](2+) Dications. A Series of [3-(eta(6)-Arene)-closo-3,1,2-FeC2B9H11] Complexes. Reliable Synthesis of Polymethylated [(eta(6)-Arene) Developed was a systematic method for the incorporation of the {(eta(6)-arene)Fe} fragment into a carborane cage. Reactions between [(eta(6)-arene)(2)Fe](PF6)(2) salts and Tl-2[nido-7,8-C2B9H11] in refluxing (CH2)(2)Cl-2 generated a series of [3-(eta(6)-arene)-closo-3,1,2-FeC2B9H11] neutral complexes with variable types of polymethylated arene ligands in the structure. The structures of durene and hexamethylbenzene complexes were established by X-ray diffraction analyses. The work also shows that the original hi temperature method for the preparation of the [(eta(6)-arene)(2)Fe](2+) dications fails for mesitylene and durene compounds, which was overcome by a reliable room-temperature modification. carbollide;iron
