Insertion of tBuNC into thorium–phosphorus and thorium–arsenic bonds: phosphaazaallene and arsaazaallene moieties in f element chemistry

Abstract

The reactivity of thorium–phosphido and thorium–arsenido bonds was probed using tert-butyl isocyanide, ^tBuNC. Reaction of (C₅Me₅)₂Th[E(H)R]₂, E = P, As; R = 2,4,6-ⁱPr₃C₆H₂, 2,4,6-Me₃C₆H₂ with ^tBuNC affords the first phosphaazaallene and arsaazaallene moieties with an f-element.
