Hydrodimerization of Methyl Acrylate Catalyzed by Halogenotris(triphenylphosphine)cobalt

Methyl acrylate was hydrodimerized in a methanolic solution by CoX(PPh3)3 (X = halogen) into dimethyl adipate.The in situ prepared cobalt complexes from cobalt halides, triphenylphosphine, and zinc gave higher yields of the hydrodimer in the presence of alkali halides.A mechanism is proposed which involves the protonation of Co(I)-methyl acrylate ?-complex to give (2-methoxycarbonylethyl)cobalt complex, followed by a further addition of methyl acrylate.

Olefin Hydroarylation Catalyzed by a Single-Component Cobalt(-I) Complex

A single-component Co(-I) catalyst, [(PPh3)3Co(N2)]Li(THF)3, has been developed for olefin hydroarylations with (N-aryl)aryl imine substrates. More than 40 examples were examined under mild reaction conditions to afford the desired alkyl-arene product in good to excellent yields. Catalysis occurs in a regioselective manner to afford exclusively branched products with styrene-derived substrates or linear products for aliphatic olefins. Electron-withdrawing functional groups (e.g., -F, -CF3, and -CO2Me) were tolerated under the reaction conditions.

Simpler and Cleaner Synthesis of Variously Capped Cobalt Nanocrystals Applied in the Semihydrogenation of Alkynes

Unlike the classical organometallic approach, we report here a synthetic pathway requiring no reducing sources or heating to produce homogeneous hexagonal-close-packed cobalt nanocrystals (Co NCs). Involving a disproportionation process, this simple and fast (6 min) synthesis is performed at room temperature in the presence of ecofriendly fatty alcohols to passivate Co NCs. Through a recycling step, the yield of Co NCs is improved and the waste generation is limited, making this synthetic route cleaner. After an easy exchange of the capping ligands, we applied them as unsupported catalysts in the stereoselective semihydrogenation of alkynes.
