    • Alkyl (aryl),6a-c silenyl,6d silyl,6e-h amide,6i and alkoxide6j complexes of transition metals have been reported to undergo exchange with alkanes (arenes, silanes, amines, and alcohols through equilibria similar to the following:6f Cp 2Ta(PMe3)SiBut2H, C 6H6, Cp2Ta-(H)(Ph)SiBut 2H, PMe3, Cp2Ta(PMe3)(Ph, H2SiBut2.
