Reactions of Fe3(CO)12 with 2-methyl-3-butyn-1-ol and 3-PENTYN-1-OL (cas 10229-10-4) under basic methanolic conditions: The crystal structures of Fe2(CO)6(μ-CO)(μ-η2-[HCC{C(CH3)2}C(O)(OCH3)]) and of (μ-H)Fe3(CO)9(μ3-η3-[H3CCC(CH2)(CH2)CO])

The reactions of Fe3(CO)12 with 2-methyl-3-butyn-2-ol and 3-PENTYN-1-OL (cas 10229-10-4) in CH3OH/KOH solution lead, respectively, to the binuclear complex Fe2(CO)6(μ-CO)(μ-η2-[HCC{C(CH3)2}C(O)(OCH3)]) (as the main product) and to the closed trinuclear hydridic complex (μ-H)Fe3(CO)9(μ3-η3-[H3CCC(CH2)(CH2)CO]) (as the unique product). The oxygenated ligands of these complexes are formed, respectively, by coupling of a formerly coordinated CO with a methoxy group and by coupling of a formerly coordinated CO with a deoxygenated alkynic residual.
