Ethyl 2-[2-(4-Nitrobenzoyl)-1H-indol-3-yl]acetate

open access: yesMolbank, 2017
Ethyl 2-[2-(4-nitrobenzoyl)-1H-indol-3-yl]acetate was prepared in good yield and characterized by the aza-alkylation/intramolecular Michael cascade reaction of (E)-ethyl 3-[2-(tosylamino)phenyl]acrylate with 2-bromo-4′′-nitroacetophenone, followed by ...

Magnetization of graphane by dehydrogenation [PDF]

open access: yesApplied Physics Letters, 2009
Using first principles calculations, we show that each hydrogen vacancy created at graphane surface results in a local unpaired spin. For domains of hydrogen vacancies the situation is, however, complex and depends on the size and geometry of domains, as well as whether the domains are single or double sided.

THE INFLUENCE OF MOLYBDENUM AND TUNGSTEN ON THE CRM-OXIDE CATALYST REACTIVITY IN PROPANE ACTIVATION: A QUANTUM MECHANICS CALCULATION [PDF]

open access: yesEuropean Journal of Materials Science and Engineering, 2020
A quantum chemical calculation for the activation of propane across CrM-oxide (M = Cr, Mo, and W) catalysts in the dehydrogenation of propane into propylene was studied. The calculation was carried out via the use of the PM3 semi-empirical approach.
