Abstract

The reaction of Ln(L)N"(2) ( Ln = Nd, Ce; L = t-BuN-CH2CH2[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).
