Selenium reagents as catalysts

Organoselenium chemistry has become an important tool in synthetic and medicinal chemistry.

B2pin2-catalyzed oxidative cleavage of a CC double bond with molecular oxygen

B₂pin₂-catalyzed oxidative cleavage of the CC double bond of an olefin with molecular oxygen as the oxidant and oxygen source has been developed.

Fabrication of Se/C using carbohydrates as biomass starting materials: an efficient catalyst for regiospecific epoxidation of β-ionone with ultrahigh turnover numbers

Fabrication of Se/C catalyst from glucose as the biomass starting materials was reported for the first time, affording an efficient and regiospecific epoxidation of β-ionone.

Transition-metal-free cleavage of C–C double bonds: a three-component reaction of aromatic alkenes with S8and amides towards aryl thioamides

A novel transition-metal-free cleavage of C–C double bonds has been developed from a three-component reaction involving aromatic alkenes, S₈and amides, generating various aryl thioamides in up to 96% yields.

Poly(N-isopropylacrylamide-co-l-proline)-catalyzed Claisen–Schmidt and Knoevenagel condensations: unexpected enhanced catalytic activity of the polymer catalyst

The heterogeneous catalyst is more active than the homogeneous one! The abnormal phenomenon is probably caused by the polymer, which enriches the reactants around the reaction sites.
