2-(Ferrocenylmethyl)-6-methoxy-3-methylbenzonitrile and 10-(Ferrocenylmethyl)phenanthrene-9-carbonitrile

The structures of the title compounds, 2-(ferrocenylmethyl)-6-methoxy-3-methylbenzonitrile, [Fe(C₅H₅)(C₁₅H₁₄NO)], (1), and 10-(ferrocenylmethyl)phenanthrene-9-carbonitrile, [Fe(C₅H₅)(C₂₁H₁₄N)], (2), revealed that the cyano groups of the arylacetonitrile migrated to the aromatic systems during aryne reactions. The orientation of the two cyclopentadienyl rings of the ferrocenyl moiety of (1) is close to a staggered conformation, while that of (2) is nearly eclipsed.
