Borane‐Catalyzed Water Dehydrogenation at Dioxaphospholes and ‐Phospholanes

Angewandte Chemie International Edition, EarlyView.
The borane‐catalyzed dehydrogenation of phenylphosphinate esters, which are formed from the reaction of dioxaphospholes and ‐phospholanes with water or air moisture under mild conditions, is reported. The mechanism of this transformation was investigated by kinetic measurements and DFT calculations, which indicate hydrogen elimination from a ...

Annatto‐Derived Carotenoids (Bixin and Norbixin) As Biodiesel Antioxidants: Characterization and Effects on Oxidative Stability (Rancimat and PetroOXY)

Journal of the American Oil Chemists' Society, EarlyView.
Annatto‐derived bixin and norbixin were characterized and evaluated as natural antioxidants for soybean biodiesel. Their antioxidant performance and effects on oxidative stability were assessed using DPPH, Rancimat, and PetroOXY methods. ABSTRACT The increasing use of eco‐friendly fuels is increasing the production of biodiesel but soybean biodiesel is
