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.
