Acetylene terminated aspartimides and resins therefrom [PDF]

, 1989
Acetylene terminated aspartimides are prepared using two methods. In the first, an amino-substituted aromatic acetylene is reacted with an aromatic bismaleimide in a solvent of glacial acetic acid and/or m-cresol.

Sulfur source-mediated transcriptional regulation of the rhlABC genes involved in biosurfactants production by Pseudomonas sp. strain AK6U

Frontiers in Microbiology, 2014
Despite the nutritional significance of sulfur, its influence on biosurfactants production has not been sufficiently studied. We investigated the expression of key biosurfactants production genes, rhlABC, in cultures of Pseudomonas sp.

Quantifying Inactive Lithium in Lithium Metal Batteries [PDF]

, 2019
Inactive lithium (Li) formation is the immediate cause of capacity loss and catastrophic failure of Li metal batteries. However, the chemical component and the atomic level structure of inactive Li have rarely been studied due to the lack of effective ...

Radikale Kaskadenreaktion, welche die Kreuzkupplung von Olefinen mit der Smiles‐Truce‐Umlagerung kombiniert

Angewandte Chemie, EarlyView.
Wir stellen eine kobaltkatalysierte Radikalkaskade vor, die zwei Alken Ausgangsstoffe effizient miteinander verbindet und so in einem einzigen Schritt mehrere Bindungen aufbaut. Der Prozess beginnt mit einem kobaltkatalysierten Wasserstoffatomtransfer an eine Styrol‐Doppelbindung, gefolgt von einer Giese‐Addition.

Ein Dithio‐Vinylthio‐C2‐Synthon, das kristalline und lumineszierende, schwefelhaltige Polymere ermöglicht

Angewandte Chemie, EarlyView.
Die Umsetzung von CaC2 zu einem modularen C2‐Baustein ermöglicht die Synthese eines α,ω‐Bis(vinylthio)‐Monomers sowie dessen Weiterumsetzung zu kristallinen, sequenzdefinierten, schwefelfunktionalisierten Polymere. Dichte Thioether‐Cluster induzieren nichtkonventionelle Lumineszenz und ermöglichen eine präzise Kontrolle der Struktur‐Eigenschafts ...
