Abstract:

We wish to report three aspects of the photochemistry of n5-C5Me5FeCO2R complexes, R Me, Et, CH2CH2SiMe3 and SiMe3, which relate to a proposed mechanism for hydorsilation catalysis. These are i photochemically induced insertion of C2H4 into the Fe-Si bond of n5-C5Me5FeCO2SiMe3, ii transfer of either the -SiMe3 group or a beta-H group upon photolysis of n5-C5Me5FeCO2CH2CH2SiMe3, and iii reductive elimination of alkane, RH, upon photoinduced oxidative addition of HSiR3 R Me, Et to n5-C5Me5FeCO2R, R Me, Et.
