A comparative study on the catalytic activity of a series of [IrCl(2)Cp*(NHC)] complexes in several C-O and C-N coupling processes implying hydrogen-borrowing mechanisms has been performed. The compound [IrCl(2)Cp*(I(nBu))] (Cp*=pentamethyl cyclopentadiene; I(nBu)=1,3-di-n-butylimidazolylidene) showed to be highly effective in the cross-coupling reactions of amines and alcohols, providing high yields
