A new imino-N-heterocyclic carbene ligand precursor [1-(2,4,6bromide has been synthesised and structurally characterised. The silver(was readily prepared by reaction with Ag 2 O. Transfer of the ligand from silver() to palladium() and rhodium() by reaction with [PdCl 2 (MeCN) 2 ] and [Rh(cod)(THF) 2 ][BF 4 ] led to the tautomerisation of the imine moiety to the enamine affording the structurally characterised complex [PdCl 2 (C ∧ enamine)] and [Rh(cod)(C ∧ enamine)][BF 4 ] respectively, where (C ∧ enamine) = 1-(2,4,6-Me 3 C 6 H 2 )imidazol-2-ylidene-3-{CH᎐ ᎐ C(t-Bu)NH(i-Pr)}.
