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

The reactivity of thorium-phosphido and thorium-arsenido bonds was probed using tert -butyl isocyanide, t BuNC. Reaction of (C 5 Me 5 ) 2 Th[E(H)R] 2 , E = P, As; R = 2,4,6- i Pr 3 C 6 H 2 , 2,4,6-Me 3 C 6 H 2 with t BuNC affords the first phosphaazaallene and arsaazaallene moieties with an f-element. The reactivity of thorium-phosphido and thorium-arsenido bonds was probed using tert -butyl isocyanide, t BuNC.
