We report the synthesis, characterisation and reactivity of the stable imidazol-2-ylidene ^EtIDip (^EtIPr), {EtCN(Dip)}₂C:, Dip = 2,6-iPr₂C₆H₃, as a chemically robust alternative to IDip (IPr), {HCN(Dip)}₂C:. The N-heterocyclic carbene ^EtIDip could be further converted to the oxidised species [^EtIDipCl]Cl, ^EtIDipF₂, ^EtIDipO, and ^EtIDipSe, and the group 13 element complexes ^EtIDipEX₃, with E = B, X = Br; E = Al, X = I; E = Ga, X = I; E = Al, X = H. The properties of the ^EtIDip and IDip ligands are compared and the molecular structures of (DipNCEt)₂, [^EtIDipH]Cl, [^EtIDipH]I, ^EtIDip, [^EtIDipCl]Cl, ^EtIDipF₂, ^EtIDipO, ^EtIDipBBr₃, ^EtIDipAlI₃, ^EtIDipGaI₃, and ^EtIDipAlH₃ have been determined.
