Regioselective C–H activation of lanthanide-bound N-heterocyclic carbenes
Literature Information
Polly L. Arnold, Stephen T. Liddle
The reaction of Ln(L)N″2 (Ln = Nd, Ce; L = t-BuNCH2CH2[C{NCHCHNt-Bu}], N″ = N(SiMe3)2) with trimethylsilyl iodide regiospecifically functionalises the carbene backbone at the C4-carbene ring position to afford the silylated complex Ln(L′)N″I; Ln(L′)N″2 is isolated after attempted reduction (L′ = t-BuNCH2CH2[C{NC(SiMe3)CHNt-Bu}]) which allows a comparison of the structurally characterised complexes Nd(L)N″2, [Nd(L′)N″I]2, and Nd(L′)N″2.
