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. 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 and further to the Fe center and the second (dicarbollide) ligand.
