ABSTRACT [reaction: see text] The molybdenum-mediated Pauson-Khand reaction promoted by Mo(CO)3(DMF)3 takes place under very mild conditions in the absence of any promoter. High yields in Pauson-Khand adducts are obtained in the cyclization of a wide variety of functionalized 1,6- and 1,7-enynes. Enynes bearing electron withdrawing groups at the alkene terminus are particularly good substrates.

    ABSTRACT: An easily accessible chiral iridium-BINAP complex can effect the cooperative processes of decarbonylation of an aldehyde and cascaded enantioselective Pauson–Khand-type reaction. A survey of ligands revealed that atropisomeric aryl-diphosphine ligands were superior to chiral alkyl-diphosphines in this dual catalysis. Applying the reaction conditions of [IrCl(COD)]2/(S)-BINAP complex with nonylaldehyde as a CO surrogate at 100°C in anhydrous dioxane solvent, various 1,6-enynes were transformed to the corresponding optically active bicyclic cyclopentenones with excellent enantioselectivities (up to 98% ee).

    ABSTRACT: The kinetics for the cobalt-catalyzed intermolecular Pauson-Khand reaction (PKR) between (trimethylsilyl)acetylene and norbornadiene (NBD) at a constant CO pressure has been studied by means of in situ FT-IR. The rate dependence on catalyst and substrate concentrations was examined, and it was found that the process is -1.9 order with respect to CO pressure, zero order with respect to acetylene, 0.3-1.2 order with respect to NBD, and 1.3 order with respect to the Co-2(CO)(8) catalyst. Catalytic reaction intermediates were examined by their corresponding metal carbonyl IR frequencies. By a one-pot consecutive Pauson-Khand experiment, the NBD-dicobalt hexacarbonyl complex was identified as a catalytically active complex. Co-4(CO)(12) was also studied as a catalyst source in the PKR. Analysis of the corresponding reaction intermediates by IR demonstrated that Co-2(CO)(8) and Co-4(CO)(12) provide identical intermediate profiles upon reaction with TMSC2H. The experimental measured kinetics are consistent with the alkene insertion being the rate-limiting step in the catalytic PKR. Finally, the effect of phosphine substitution on the catalyst and the use of Lewis acid additives were shown to have a deleterious effect on the reaction rate.

    ABSTRACT: Organocobalt compounds in organic synthesis have three characteristic reactions. The first occurs because cobalt has a high affinity to carbon–carbon π-bonds or carbon–nitrogen π-bonds. The second occurs because cobalt has a high affinity to carbonyl groups. The third is due to cobalt easily tending to form square-planar bipyramidal six-coordination structures with four nitrogen atoms or two nitrogen atoms and two oxygen atoms at the square-planar position, and to bond with one or two carbon atoms at the axial position. The first characteristic reactions are the representative reactions of organocobalt compounds with a mutually bridged bond between the two π-bonds of acetylene and the cobalt–cobalt bond of hexacarbonyldicobalt. These are reactions with a Co2(CO)6 protecting group to reactive acetylene bond, the Nicholas reactions, the Pauson–Khand reactions ([2 + 2 + 1] cyclizations), [2 + 2 + 2] cyclizations, etc. These reactions are applied for the syntheses of many kinds of pharmaceutically useful compounds. The second reactions are carbonylations that have been used or developed as industrial processes such as hydroformylation for the manufacture of isononylaldehyde, and carbonylation for the production of phenylacetic acid from benzyl chloride. The third reactions are those reactions with the B12-type catalysts, and they have recently been used in organic syntheses and are utilized as catalysts for stereoselective syntheses. These reactions have been used as new applications for organic syntheses. Copyright © 2007 John Wiley & Sons, Ltd.
