The reactions of Fe3(CO)12 with 2-methyl-3-butyn-2-ol and 3-pentyn-1-ol in CH3OH/KOH solution lead, respectively, to the binuclear complex Fe2(CO)6(mu-CO)(mu-eta2-[HCC{=C(CH3)2}C(=O)(OCH3)]) (as the main product) and to the closed trinuclear hydridic complex (mu-H)Fe3(CO)9(mu-eta3-[H3CCC(CH2)(CH2)CO]) (as the unique product).

Abstract
The reactions of Fe3(CO)12 with 2-methyl-3-butyn-2-ol and 3-pentyn-1-ol in CH3OH/KOH solution lead, respectively, to the binuclear complex Fe2(CO)6(mu-CO)(mu-eta2-[HCC{=C(CH3)2}C(=O)(OCH3)]) (as the main product) and to the closed trinuclear hydridic complex (mu-H)Fe3(CO)9(mu-eta3-[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.File in questo prodotto:
