Prop-2-ynyl alcohol as a precursor to the η1-ethenyl ligand
Abstract
In the presence of water the unsaturated iridium(III) metallacyclopentadiene halide complex [graphic omitted]R)(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 [graphic omitted]R)(PPh3)2(CO)(η1-CH
CH2)(3, R = CO2Me) in quantitative yield.
