Abstract

The photoreaction between C₅H₅Fe(CO)₂Si(CH₃)₃ (I) and cyclohexyl isocyanide leads to the sequential replacement of both carbonyl groups by the isocyanide. Both the racemic monosubstituted product, C₅H₅Fe(CO)(C₆H₁₁NC)Si(CH₃)₃ (II) and the disubstituted product, C₅H₅Fe(C₆H₁₁NC)₂Si(CH₃)₃ (III) have been isolated and characterized. Photoreaction between the disubstituted product III and C₅H₅Fe(CO)₂Si(CH₃)₃ in a sealed tube gives the monosubstituted product, II. Thermal initiation of the above reactions failed. The disubstituted product III is stable under both the thermal and photochemical conditions used; thus, insertion of isocyanide into FeSi bond was observed not to occur.
