Multi-electron redox reactivity of a thorium(ii) hydride synthon.

ABSTRACT: Molecular thorium complexes are dominated by stable tetravalent thorium, while subvalent thorium and the relevant synthons are very limited. Herein, we report that hydrogenolysis of the half-sandwich penta-arylcyclopentadienyl-supported thorium tribenzyl complex [(Cp^Ar5)Th(p-CH₂-C₆H₄-Me)₃] (1) (Cp^Ar5 = C₅Ar₅, Ar = 3,5-ⁱPr₂-C₆H₃) affords the double-sandwich bimetallic hydride complex [(Cp^Ar5)Th(μ-H)]₂ (2), in which one of the five aryl groups in the Cp^Ar5 ligand is selectively reduced to a puckered di-anionic 1,4-cyclohexadienyl. Complex 2 can be regarded as a thorium(ii) hydride synthon, and exhibits unique redox-active
