Synthesis and Reactivity of a Scandium Terminal Hydride: H-2 Activation by a Scandium Terminal Imido Complex

Abstract : Dihydrogen is easily activated by a scandium terminal imido complex containing the weakly coordinated THF. The reaction proceeds through a 1,2-addition mechanism, which is distinct from the sigma-bond metathesis mechanism reported to date for rare-earth metal-mediated H-2 activation. This reaction yields a scandium terminal hydride, which is structurally well-characterized, being the first one to date. The reactivity of this hydride is reported with unsaturated substrates, further shedding light on the existence of the terminal hydride complex. Interestingly, the H-2 activation can be reversible. DFT investigations further eludciate the mechanistic aspects of the reactivity of the scandium anilido-terminal hydride complex with PhNCS but also on the reversible H-2 activation process.
