Transition Metal Silyl Complexes, 44. — Preparation of the Binuclear Silyl Complexes (CO)~3~(R~3~Si)Fe(μ‐PR′R′′)Pt(PPh~3~)~2~ by Oxidative Addition of (CO)~3~(R′R′′HP)Fe(H)SiR~3~ to (C~2~H~4~)Pt(PPh~3~)~2~
The complexes (CO)~3~(R′R′′HP)Fe(H)SiR~3~ (1) [PHR′R′′ = PHPh~2~, PH~2~Ph, PH~2~Cy; SiR~3~ = SiPh~3~, SiPh~2~Me, SiPhMe~2~, Si(OMe)~3~] react with Pt(C~2~H~4~)(PPh~3~)~2~ to give the dinuclear, silyl‐substituted complexes (CO)~3~(R~3~Si)Fe(μ‐PR′R′′)Pt(PPh~3~)~2~ (2) in high yields. Upon reaction of 2 (R = R′ R′′ = Ph) with CO, the PPh~3~ ligand at Pt being trans to the PPh~2~ bridge is exchanged, and (CO)~3~(Ph~3~Si)Fe(μ‐PPh~2~)Pt(PPh~3~)CO (3) is formed. Complex 3 is characterized by an X‐ray structure analysis. The rather short Fe — Si distance [233.9(2) pm] and the infrared spectrum of 3 indicate that the Fe — Pt bond is quite polar.
