In addition to zerovalent Group 10 metals, ansa-molybdenocene dihydride reacted with nitriles upon liberation of dihydrogen by photoirradiation (Scheme 1.21) [31]. Acetonitrile underwent oxidative addition of the C-CN bond to the molybdenum center. On the other hand, when the complex was treated with bulkier pivalonitrile, the side-on coordination complex was formed. 

Hydride transfer reactions from [Cp2MoH2] were discussed above in studies by Ito et al. [38], where this molybdenum dihydride was used in conjunction with acids for stoichiometric ionic hydrogenations of ketones. Tyler and coworkers have extensively developed the chemistry of related molybdenocene complexes in aqueous solution [52-54]. The dimeric bis-hydroxide bridged dication dissolves in water to produce the monomeric complex shown in Eq. (32) [53]. In D20 solution at 80 °C, this bimetallic complex catalyzes the H/D exchange of the a-protons of alcohols such as benzyl alcohol and ethanol [52, 54].
