Abstract:The high stability of the + IVoxidation state limits thorium redox reactivity. Here we report the synthesis and the redox reactivity of two Th(IV) complexes supported by the arene‐tethered tris(siloxide) tripodal ligands [(KOSiR2Ar)3‐arene)]. The two‐electron reduction of these Th(IV) complexes generates the doubly reduced [KTh((OSi(OtBu)2Ar)3‐arene)(THF)2] (2OtBu) and [K(2.2.2‐cryptand)][Th((OSiPh2Ar)3‐arene)(THF)2](2Ph‐crypt) where the formal oxidation state of Th is +II.
