In the presence of water the unsaturated iridium(III) metallacyclopentadiene halide complex cyclo(PPh3)2Cl (1, R = CO2Me) undergoes reaction with prop-2-ynyl alcohol, or methyl prop-2-ynyl ether at room temperature to give the η1-ethenyl complex cyclo(PPh3)2(CO)(η1-CH=CH2) (3, R = CO2Me) in quantitative yield.

The reactions of [κ2(C1,C4)-CR{double bond, long}CRCR{double bond, long}CR](PPh3)2Ir(Cl) (9, R = CO2Me) with propargyl alcohol derivatives (2-propyn-1-ol, 2-methyl-3-butyn-2-ol, 1-ethynylcyclopentanol, and 1-ethynylcyclooctanol), in the presence of water leads to the formation of iridium(III)-vinyl complexes bearing the general structure [κ2(C1,C4)-CR{double bond, long}CRCR{double bond, long}CR](PPh3)2Ir(CO)(κ1-vinyl) where vinyl = -CH{double bond, long}CH2, -(E)-CH{double bond, long}CHMe, -CH{double bond, long}C(CH2)4, or -CH{double bond, long}C(CH2)7. In these, the CO ligand was derived from the terminal carbon of the starting alkyne and the oxygen atom from water. Under anhydrous conditions, 9 undergoes reaction with 2-propyn-1-ol to give trimethyl 1,3-dihydro-3-oxo-4,5,6-isobenzofurantricarboxylate, the result of a cycloaromatization/transesterification involving the buta-1,3-dien-1,4-diyl ligand in 9 and 2-propyn-1-ol.
