Abstract

A new ferrocenyl-N-heterocyclic carbene ligand precursor 1,1'-bis[(1-tert-butylimidazolium)-3-methyl]ferrocene dichloride has been synthesised and structurally characterised. The imidazolium salt was readily deprotonated in situ with KN(SiMe3)(2) and reacted with [PdCl2 (cod)] to afford the structurally characterised palladium (II) complex trans-[PdCl2(CfcC)], where (cod) = 1,5-cyclooctadiene and (CfcC) = 1,1'-di-tert-butyl-3,3'-(1,1'-dimethyleneferrocenyl)-diimidazol-2-yliden e.
