Dual Nickel/Titanium Catalyzed Cross‐Electrophile Coupling of Thioesters with Benzylic Alcohols

open access: yesChemCatChem, EarlyView.
A nickel‐catalyzed and Lewis acid‐assisted cross‐electrophile coupling between thioesters and electron‐rich benzylic alcohols is described. A series of investigations delivers insights into the mechanism of this transformation. While the thioester is most likely activated through oxidative addition to Ni(0), the alcohol is converted to the ...

The Electrochemical Characterization of Functionalized Isoindolinones

open access: yesChemElectroChem, EarlyView.
A new class of redox organic molecules called isoindolinones are evaluated electrochemically for their use in high‐voltage nonaqueous organic flow batteries. The molecules are characterized by a reversible and highly negative formal potential in the region of −2.8 V versus ferrocene/ferrocenium.

Understanding CO_2 capture mechanisms in aqueous hydrazine via combined NMR and first-principles studies [PDF]

open access: yes, 2017
Aqueous amines are currently the most promising solution for large-scale CO_2 capture from industrial sources. However, molecular design and optimization of amine-based solvents have proceeded slowly due to a lack of understanding of the underlying ...

Asymmetric Total Synthesis of (+)‐ and (−)‐Myrioneurinol Employing a “Resolutive” Late‐Stage Barton‐McCombie Deoxygenation

open access: yesChemistry – A European Journal, Volume 31, Issue 30, May 27, 2025.
The total syntheses of (+)‐ and (−)‐myrioneurinol are described. This was achieved through two key steps based on a Prins‐type alkenylation of activated phenols to construct the central cycle of this natural substance, and a late‐stage “resolutive” Barton Mc‐Combie reaction which allowed the separation as well as the deoxygenation of both enantiomers ...

Deteccion de plaguicidas en vegetales de costa rica mediante la inhibicion de colinesterasas humanas

open access: yesArchivos Latinoamericanos de Nutrición, 2004
Mediante un método sencillo y de bajo costo basado en la inhibición de la actividad de las colinesterasas sérica y eritrocítica, se detectó la presencia de plaguicidas organofosforados y/o carbamatos en lechuga (Lactuca sativa), culantro (Coriandum ...
