A Ferrocenyl‐Backboned Unsymmetric O,C‐Coordinating Ligand and Its Tin Derivatives

AbstractThe syntheses of the phosphonyl‐substituted ferrocenyl stannane Fe[{η5‐C5H3‐1‐SnPh3‐2‐P(O)(O‐iPr)2}{η5‐C5H4P(O)(O‐iPr)2}] (1) and its iodine derivative Fe[{η5‐C5H3‐1‐SnPh2I‐2‐P(O)(O‐iPr)2}{η5‐C5H4P(O)(O‐iPr)2}] (2) are reported. The syntheses of the corresponding salts Fe[{η5‐C5H3‐1‐SnPh2‐2‐P(O)(O‐iPr)2}{η5‐C5H4P(O)(O‐iPr)2}]X (3, X=Al{OC(CF3)3}4, 4, X=ClO4, 5, X=HgI3), respectively, are also described. The compounds are characterized by elemental analyses, 1H, 13C, 31P, 119Sn NMR and IR spectroscopy, electrospray ionization mass spectrometry, and, except for 4 and 5, single‐crystal X‐ray diffraction analyses.
