Photochemistry of Iron and Ruthenium Carbonyl Complexes: Evidence for Light-Induced Loss of Carbon Monoxide and Reductive Elimination of Triethylsilane from cis-mer-HM(SiEt3)(CO)3(PPh3)

摘要

Detailed studies of cis-mer-HM(SiEt3)(CO)3(PPh3) (M = Ru, Fe) show that near-UV irradiation can result in reductive elimination of Et3SiH as a primary photoprocess. Additionally, qualitative 298 K experiments show that Ph3SiH, (MeO)3SiH, (EtO)3SiH, and MeCl2SiH can be reductively eliminated from the appropriate cis-mer metal complex, establishing elimination of R3SiH as a viable process for a wide range of R.
