Abstract

A new imino-N-heterocyclic carbene ligand precursor [1-(2,4,6-Me3C6H2) imidazolium-3-{CH2C(t-Bu)=N(i-Pr)}] bromide has been synthesised and structurally characterised. The silver(I) complex [Ag(C(boolean AND)imine)(2)] AgBr2, where (C(boolean AND)imine) = 1-(2,4,6- Me3C6H2) imidazol-2-ylidene-3-{CH2C(t-Bu)=N(i- Pr)}, was readily prepared by reaction with Ag2O. Transfer of the ligand from silver(I) to palladium(II) and rhodium(I) by reaction with [PdCl2(MeCN)(2)] and [Rh(cod)(THF)(2)][BF4] led to the tautomerisation of the imine moiety to the enamine affording the structurally characterised complex [PdCl2(C(boolean AND)enamine)] and [ Rh( cod)(C(boolean AND)enamine)][BF4] respectively, where (C(boolean AND)enamine) = 1-(2,4,6-Me3C6H2) imidazol-2-ylidene-3-{CH=C(t-Bu) NH(i-Pr)}.
