Abstract: | The arene salts (arene)2Fe](PF6)2 (arene = mesitylene 1a, and hexamethylbenzene, 1c) react readily with AlMe3 in dichloromethane or dibromomethane to produce the novel exo-halomethyl-η5-cyclohexadienyl salts (η5-exo-CH2XC6H3Me3)(η6-C6H3Me3)Fe]PF6 (X = Cl, 2d; X = Br, 2e) and (η5-exo-CH2XC6Me6)(η6-C6Me6)Fe]PF6 (X = Cl, 2f; X = Br, 2g) which have been characterized spectroscopically and, in the case of 2f, crystallographically. |
