NiH-Catalyzed Enantio- and Regioselective Hydroselenylation of Unactivated Alkenes. [PDF]

Adv Sci (Weinh)
Nickel‐hydride‐catalyzed enantio‐ and regioselective hydroselenylation of unactivated alkenes provides access to chiral organoselenium compounds. Enantiodetermining Ni–H insertion followed by single‐electron diselenide activation generates selenyl radical.

Lewis Acid Site Engineering in MOF‐Derived Aluminum Oxide/Carbon Composites for Dechlorination of Waste Plastic Pyrolysis Oil

Advanced Functional Materials, EarlyView.
Controlled carbonization of an Al‐MOF partially decomposes its linkers, exposing coordinatively unsaturated Al centers within an oxide/carbon composite. The resulting Lewis acid sites, rather than surface area, govern organochlorine capture: the composite removes chemically diverse organochlorines from waste plastic pyrolysis oil, outperforms a ...

Alkene Isomerization using a Heterogeneous Nickel-Hydride Catalyst [PDF]

Transition metal-catalyzed alkene isomerization is an enabling technology used to install an alkene distal to its original site. Due to their well-defined structure, homogeneous catalysts can be fine-tuned to optimize reactivity, stereoselectivity, and ...

Trichloroisocyanuric Acid: An Alternate Green Route for the Transformation of Alkenes into Epoxides

Journal of the Brazilian Chemical Society, 2002
The preparation of epoxides is efficiently achieved in mild conditions by reaction of alkenes with trichloroisocyanuric acid in aqueous acetone followed by treatment of the resulting chlorohydrin with aqueous KOH in ether / pentane.

Gold-alkene complexes

, 2012
In the last two decades, the activation of C–C multiple bonds by gold catalysts has received considerable attention [1]. Most of the applications have concerned the addition of carbon-, nitrogen- and oxygen-nucleophiles to the multiple bond of alkynes [2]
