COMPLEXES OF DECAMETHYLSILICOCENE - CP2-ASTERISK-SI(CO) AND CP2-ASTERISK-SI(N2)

The synthesis and IR spectroscopic detection of the monocarbonyl and mononitrogen complex of decamethylsilicocen in liquid xenon (LXe) and liquid nitrogen (LN2) is reported. The reactions were found to be highly incomplete under a few bar of CO or N2 and reversibel when the pressure is released. Cp2*Si(CO) is characterized by three isotopomeres and Cp2*Si(N2) was synthesized on two independent routes.
