Deprotektive Alkylierung: Eine Plattform zur Umsetzung von Alkoholen zu Aminen mittels Nonafluormesitylensulfonamiden

open access: yesAngewandte Chemie, EarlyView.
Die direkte Umwandlung von Alkoholen in tertiäre oder sekundäre Amine in einem Reaktionsschritt unter Verwendung von Nms‐Amiden wird beschrieben. Die Transformation zeichnet sich durch eine breite Toleranz gegenüber verschiedenen funktionellen Gruppen und eine hohe Stereospezifität aus, was ihre Eignung für die Synthese isotopenmarkierter Arzneimittel ...

Grenzflächen‐Synergie zwischen Mn und Kohlenstoffnitrid ermöglicht die selektive photokatalytische C–H‐Chlorierung mittels Einzelatomkatalyse

open access: yesAngewandte Chemie, EarlyView.
Ein Mangan‐Einzelatom‐Photokatalysator auf funktionalisiertem Kohlenstoffnitrid ermöglicht die selektive, durch sichtbares Licht angetriebene C(sp2)–H‐Chlorierung. DFT‐gestützte mechanistische Untersuchungen zeigen, dass die photoinduzierte Ladungstrennung NCS aktiviert, während isolierte Mn‐Zentren Mn–Cl‐Intermediate an der Katalysatorgrenzfläche ...

Study of the Impact of LPG Composition on the Blowoff and Flashback Limits of a Premixed Flame in a Swirl Burner [PDF]

open access: yesJournal of Applied Fluid Mechanics
Liquefied petroleum gas (LPG) is considered one of the gases widely used in many industrial and residential sectors. Still, due to its different compositions, mainly propane (C3H8) and butane (C4H10), it can have other combustion characteristics.

Analysis of Natural Vaporization in LPG Tanks

open access: yesEngineering Proceedings
Natural vaporization in LPG (liquefied petroleum gas) tanks refers to the process where liquid LPG is converted to vapor naturally due to ambient heat. This natural vaporization process relies on ambient heat from the surroundings, which is transferred ...
