A versatile, monoanionic, chelating (bis)carbene ligand (2) was used to prepare a thorium dihalide complex (3) and a direduced-bpy derivative (4).: CASSCF calculations suggest the involvement :of a multiconfigurational open-shell singlet, with the main configuration corresponding to a Th(III), bpy(-1) (f(1)pi*(1)) electronic structure. The reactivity of 4 was explored in. various transformations, including reactions with carbonyls and organic azides; the latter gave rise to an unusual terminal Th-imido bpy complex (6).
