The reactions of 2 with FeCl2 and SnCl2 result in the formation of deca(4-methylbenzyl)ferrocene (3) and deca(4-methylbenzyl)stannocene (4), respectively. The 1H and 13C NMR, IR and mass spectra of the new compounds as well as the single crystal X-ray structure analysis of 1 are reported and discussed.de540 Chemie und zugeordnete WissenschaftenCyclopentadieneFerroceneStannoceneArticle1865-7117
