Polymethylated [Fe(eta(6)-arene)(2)](2+) dications: methyl-group rearrangements and application of the EINS mechanism

Original language description

Reactions between the methylated arenes ArMen [where ArMen = C6MenH(6-n), and n = 1-6] and FeCl2 in heptane at 90 degrees C in the presence of anhydrous AlCl3 give, for the arenes with n = 1-5, extensive isomerisations and disproportionations involving the methyl groups on the arene rings, and the formation of mixtures of [Fe(ArMen)(2)](2+) dications that defy separation into pure species. GC-MS studies of AlCl3/mesitylene and AlCl3/durene reactions in the absence of FeCl2 (90 degrees C, 2 h) allow quantitative assessments of the rearrangements, and the EINS mechanism (electrophile-induced nucleophilic substitution) is applied to rationalise the phenomena. By contrast, ArMen/FeCl2/AlCl3 reactions in heptane for 24-36 h at room-temperature proceed withno rearrangements, allowing the synthesis of the complete series of pure [Fe(ArMen)](2+) cations in yields of 48-71%.
