- 2,2,3,3-tetrafluoronickelacyclopentanes generated via the oxidative cyclization of tetrafluoroethylene and simple alkenes: A key intermediate in nickel-catalyzed C-C bond-forming reactions
-
Oxidative cyclization of tetrafluoroethylene (TFE) and ethylene with Ni(0) resulted in the formation of a five-membered nickelacycle. In the presence of PPh3 as an auxiliary ligand, the partially fluorinated five-membered nickelacycle was isolated and the structure was determined by X-ray analysis. This nickelacycle was found not only to react stoichiometrically with enones to give a cross-trimerization product but also to be a key reaction intermediate in the Ni(0)-catalyzed cotrimerization of TFE and ethylene, leading to 5,5,6,6-tetrafluoro-1-hexene.

- Expanding the regioselective enzymatic repertoire: Oxidative mono-cleavage of dialkenes catalyzed by Trametes hirsuta
-
The first report of a biocatalytic regioselective oxidative mono-cleavage of dialkenes was successfully achieved employing a cell-free enzyme preparation from Trametes hirsuta at the expense of molecular oxygen. Selected reactions were performed on a preparative scale affording high to excellent conversions and chemoselectivities. The Royal Society of Chemistry 2012.
