Three different Ir(III) complexes with pyrene-containing N-heterocyclic carbenes have been prepared and
characterized. Two complexes contain a monodentate pyrene-imidazolylidene ligand, and have the formulae
[IrCp*Cl2(pyrene-NHC)] and [IrCp*(CO3)(pyrene-NHC)]. The third complex is a dimetallic complex
with a pyrene-di-imidazolylidene bridging ligand, with the formula [{IrCp*(CO3)}2(μ-pyrene-di-NHC)]. The
catalytic activity of the three complexes was tested in the H/D exchange of organic substrates, and in the
β-alkylation of 1-phenylethanol with primary alcohols. In the deuteration of organic substrates, the carbonate
complexes are active even in the absence of additives. The dimetallic complex is the most active
one in the catalytic coupling of alcohols, a result that may be interpreted as a consequence of the cooperativity
between the two metal centres.
