Oxidative Heck desymmetrisation of 2,2-disubstituted cyclopentene-1,3-diones [PDF]

open access: yes, 2015
Oxidative Heck couplings have been successfully developed for 2,2-disubstituted cyclopentene-1,3-diones. The direct coupling onto the 2,2-disubstituted cyclopentene-1,3-dione core provides a novel expedient way of enantioselectively desymmetrising all ...

Dispersion‐Enhanced Nitrogen‐Centered Photocatalysis of the Direct Hydrogen Atom Transfer

open access: yesAngewandte Chemie, Volume 138, Issue 6, 2 February 2026.
Nitrogen‐centered acridine photocatalysts for direct hydrogen atom transfer have been developed, leveraging dispersion interactions to enhance photocatalytic activity. This approach enables diverse functionalization reactions of strong C─H bonds even under cryogenic conditions and provides a new strategy for boosting the efficiency of direct HAT ...

Extension of the single-event microkinetic model to alkyl substituted monoaromatics hydrogenation on a Pt catalyst [PDF]

open access: yes, 2012
The Single-Event Micro Kinetic (SEMK) methodology, which had been successfully applied to benzene hydrogenation on a Pt catalyst, has now been extended toward substituted monoaromatics, that is, toluene and o-xylene.

Experimental Determination of the Equilibrium Conditions of Binary Gas Hydrates of Cyclopentane + Oxygen, Cyclopentane + Nitrogen, and Cyclopentane + Hydrogen [PDF]

open access: yesIndustrial & Engineering Chemistry Research, 2010
In this work, four-phase hydrate equilibrium data for each of the systems cyclopentane (CP) + water + hydrogen, CP + water + nitrogen, and CP + water + oxygen were measured and are reported in the temperature range of 281.3-303.1 K and the pressure range of 2.27-30.40 MPa. Measurements were made using an isochoric method.
