Asymmetric Hydrogenation and Catalysis

Reaction of the dimolybdenum tetraimido complex [(MeC5H4)Mo(NPh)(μ-NPh)]2 with an excess of para-tolyl isocyanate results in the stepwise exchange of terminal imido ligands to yield [(MeC5H4)2Mo2(N-p-tolyl)(NPh)(μ-NPh)2] and [(MeC5H4)Mo(N-p-tolyl)(μ-NPh)]2. Prolonged heating does not, however, result in substitution of the bridging phenylimido ligands.
