Additive Character of Electron Donation by Methyl Substituents within a Complete Series of Polymethylated [1-(eta(6)-Me(n)C(6)H(6-n))-closo-1,2,3-FeC(2)B(9)H(11)] Complexes. Linear Correlations of the NMR Parameters and Fe(II/III) Redox Potentials...

Popis výsledku v původním jazyce

A systematic method for the incorporation of the {(eta(6)-Me(n)C(6)H(6-n))Fe} fragment into the dicarbollide cage was developed based on reactions between [(eta(6)-Me(n)C(6)H(6-n),)(2)Fe][PF(6)](2) salts (1) and Tl(2)[nido-7,8-C(2)B(9)H(11)]. These reactions proceed with elimination of one arene ligand to generate a complete series of the neutral [1-(eta(6)-Me(n)C(6)H(6-n))-closo-1,2,3-FeC(2)B(9)H(11)] (2) complexes with n=1-6 in yields ranging 15 70% depending on the arene. The structures of mesityleneand pentamethylbenzene complexes were established by X-ray diffraction analyses. All compounds were characterized by (11)B and (1)H NMR measurements, mass spectra, melting points and elemental analyses. Correlations between selected and (11)B NMR parameters and the Fe(II/III) redox potentials and the number of arene methyls for complexes 2 are linear. These facts establish direct evidence for a strictly additive character of electron donation by the methyl substituents to the arene ring
