Iridium(I) N-heterocyclic carbene complexes of formula Ir(κ2 O,O'-BHetA)(IPr)(η2 -coe) [BHetA=bis-heteroatomic acidato, acetylacetonate or acetate; IPr=1,3-bis(2,6-diisopropylphenyl)imidazolin-2-carbene; coe=cyclooctene] have been prepared by treating Ir(κ2 O,O'-BHetA)(η2 -coe)2 complexes with IPr. These complexes react with 2-vinylpyridine to afford the hydrido-iridium(III)-alkenyl cyclometalated derivatives IrH(κ2 O,O'-BHetA)(κ2 N,C-C7 H6 N)(IPr) through the iridium(I) intermediate Ir(κ2 O,O'-BHetA)(IPr)(η2 -C7 H7 N
