- Enantioselective Preparation of δ-Valerolactones with Horse Liver Alcohol Dehydrogenase
Alba Díaz-Rodríguez, Javier Iglesias-Fernández, Carme Rovira and Vicente Gotor-Fernández
Article first published online: 9 DEC 2013 | DOI: 10.1002/cctc.201300640
Not just horsing around: Horse liver alcohol dehydrogenase is found to be a versatile biocatalyst for the desymmetrization of 3-arylpentane-1,5-diols through a two-step one-pot oxidation. The catalytic performance of horse liver alcohol dehydrogenase (HLADH) is studied with several cofactor regeneration systems and cosolvents. Docking studies reveal the importance of pattern substitution in the selectivity and activity of this biotransformation.

One door opens and the ring closes: The combination of a ruthenium–arene complex, a noncoordinating salt, and a Lewis acid facilitates access to a highly active and selective in situ metathesis catalyst. The catalyst is formed from an inexpensive ruthenium precursor and olefins are used as the substrates. RCM=Ring-closing metathesis, acac=acetylacetonate.
- One-Pot Conversion of Carbon Dioxide, Ethylene Oxide, and Amines to 3-Aryl-2-oxazolidinones Catalyzed with Binary Ionic Liquids

Hit the pot! An effective one-pot method for the conversion of carbon dioxide, ethylene oxide, and amines to 3-aryl-2-oxazolidinones catalyzed with binary ionic liquids has been developed. This method consists of two parallel reactions and a subsequent cascade reaction between the two products of the corresponding parallel reactions.
- In Situ Observation of Cu–Ni Alloy Nanoparticle Formation by X-Ray Diffraction, X-Ray Absorption Spectroscopy, and Transmission Electron Microscopy: Influence of Cu/Ni Ratio

Peek-a-boo, Ni Cu: Silica-supported, bimetallic Cu–Ni nanomaterials with different ratios of Cu to Ni are prepared by incipient wetness impregnation without a separate calcination before reduction. TEM, XRD, and X-ray absorption spectroscopy are used to follow the reduction and alloy formation in situ. A strong interaction is found between Cu and Ni species, which results in improved reducibility of the Ni species compared with monometallic Ni.
- The Effect of Nitrogen on the Autoreduction of Cobalt Nanoparticles Supported on Nitrogen-Doped Ordered Mesoporous Carbon for the Fischer–Tropsch Synthesis
Yifei Yang, Dr. Litao Jia, Dr. Bo Hou, Prof. Debao Li, Dr. Jungang Wang and Prof. Yuhan Sun
Article first published online: 4 DEC 2013 | DOI: 10.1002/cctc.201300897
Doped-up cobalt: Cobalt nanoparticles are supported on the nitrogen-doped ordered mesoporous carbon (OMC), and its autoreduction behavior on carbon substrates is greatly improved owing to the formation of uniform cobalt particles. The autoreduced catalysts demonstrate an increasing catalytic activity in the Fischer–Tropsch synthesis.
