• Rhenium- and Manganese-Catalyzed Insertion of Alkynes into a Carbon-Carbon Single Bond of Cyclic and Acyclic 1,3-Dicarbonyl Compounds

  presence of a catalytic amount of a rhenium or manganese complex gives ring‐expanded and carbon‐chain extension products, respectively. In these reactions, alkynes insert into a non‐strained carbon–carbon single bond of 1,3‐dicarbonyl compounds. The ring‐expansion reaction is also promoted by the addition of 4‐Å molecular sieves instead of a catalytic amount of an isocyanide.

  the position of C-C bond formation on the acetylene moiety. In most of the cases, the reaction requires less than 1-mol % loading of the catalyst and does not require solvent. The reaction tolerates a wide variety of functional groups including ester, ether, allylic halide, furan, thiophene, and protected amine. Experimental and theoretical studies suggested that the reaction proceeds via a concerted

  active methylene compounds to terminal alkynes has been expanded to use malonates and low boiling terminal alkynes to form the Markovnikov addition products. Indium(III) chloride and indium(III) bromide were also found to be efficient catalysts. Knoevenagel condensation products were isolated when reactions involved a simple malonate or β-ketoester.

  The gold-catalyzed intermolecular addition of 1,3-dicarbonyl compounds to unactivated 1-alkynes (Nakamura reaction) is achieved at room temperature for the first time through synergistic gold/gallium catalysis. The developed system is highly efficient with a gold catalyst loading that can be as low as 500 ppm.
