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.
