Synthesis and structure of diiron compounds containing both diphenylphosphido and ethenyl bridges. Crystal structure of [Fe2 (CO) 6 (μ-PPh2 (μ-CPh CPhH)]
Abstract Treatment of [Fe 2 (CO) 6 (μ-CO)(μ-CR CR′ H)]−(R= R′= Ph, H an R Ph, R′=
Me) with PPh 2 Cl in CH 2 Cl 2 in the presence of TlBF 4 gives complexes of the type [Fe 2
(CO) 6 (μ-PPh 2)(μ-CR CR′ H)], containing both phosphido and ethenyl bridges. Similar
products were isolated from the reaction of [Fe 2 (CO) 6 (μ-CO)(μ-PPh 2)]− with CF 3 COOH
and acetylenes. The crystal structure of the complex [Fe 2 (CO) 6 (μ-PPh 2)(μ-CPH CPhH)]
is reported.
