Insertion, protonolysis and photolysis reactivity of a thorium monoalkyl amidinate complex.

ABSTRACT: The reactivity of the thorium monoalkyl complex Th(CH₂SiMe₃)(BIMA)₃ [1, BIMA = MeC(NⁱPr)₂] with various small molecules is described. While steric congestion prohibits the insertion of N,N'-diisopropylcarbodiimide into the Th-C bond in 1, the first thorium tetrakis(amidinate) complex, Th(BIMA)₄ (2), is synthesized via an alternative salt metathesis route. Insertion of p-tolyl azide leads to the triazenido complex Th[(p-tolyl)NNN(CH₂SiMe₃)-κ²N^1,2](BIMA)₃ (3), which then undergoes thermal decomposition to the amido species Th[(p-tolyl)N(SiMe₃)](BIMA)₃ (4). The reaction of
