The reaction of [IrCl(CO)(PPh3)2] with LiSeC≡CR (R = C6H4Me-4) provides [Ir(SeC≡CR)(CO)-(PPh3)2] (1), which undergoes oxidative addition reactions with oxygen, methyl iodide, benzeneselenenyl chloride and bis(4-tolylethynyl)mercury to provide the complexes [Ir(SeC≡CR)(η-O2)(CO)(PPh3)2] (2), [Ir(CH3)-(SeC≡CR)I(CO)(PPh3)2] (3), [Ir(CH3)I2(CO)(PPh3)2] (4), [IrCl(SePh)(SeC≡CR)(CO)(PPh3)2] (5), and [Ir(C≡CR)-(HgC≡CR)(SeC≡CR)(CO)(PPh3)2] (6). The complexes 1-3, and 5, and 6 each contain the alkyneselenolate ligand bound to iridium in a monodentate manner through selenium.
