Crystallographic and Computational Analysis of Oxyma B Cocrystals with Nitrogen-Containing Coformers: The Relevant Role of <em>n</em> → π* Interactions in Their Diverse Supramolecular Architectures
Three new cocrystals of Oxyma-B, an important racemization suppressor for peptide synthesis, with 6-methylquinoline (I), 2,3,5,6-tetramethylpyrazine (II), and 1,10-phenanthroline (III) were synthesized and their single ...
Computational Study of a Copper-Catalyzed Synthesis of Fluoroalcohols from Alkylboranes and Ketones
Fluoroalcohols are a class of organic compounds containing one or more fluorine atoms together with an alcohol group in their molecular structure. These fluorinated species have a wide range of applications due to their ...
Kinetico-mechanistic insights into the photodynamic process of AuI complexes with the CNC6H4NNC6H5 (iso-Ph) azobenzene ligand
A family of neutral isocyanide monoazo AuI complexes [AuCl(iso-Ph)], [Au(C6F5)(iso-Ph)] and [Au(C[triple bond, length as m-dash]Cpy)(iso-Ph)] (iso-Ph being CN–C6H4–N[double bond, length as m-dash]N–Ph) and a closely related ...
Confronting positions: para- vs. meta-functionalization in triindole for p-type air-stable OTFTs
The 5,10,15-trihexyl-10,15-dihydro-5H-diindolo[3,2-a:3′,2′-c]carbazole core, namely triindole, is well-known for its prominent hole-transporting properties and air stability. The functionalization of this core is also ...
Multi-Length Scale Communication Effects in Catalysis: Thinking Big and Acting Small
The use of hierarchically structured materials as catalysts has been finding increasing application in the past years. For these catalytic systems, not only the nano-scale matters: a high degree of order across multiple ...
MAF amplification licenses ERα through epigenetic remodelling to drive breast cancer metastasis.
MAF amplification increases the risk of breast cancer (BCa) metastasis through mechanisms that are still poorly understood yet have important clinical implications. Oestrogen-receptor-positive (ER+) BCa requires oestrogen ...
Peptide-Platinum(IV) Conjugation Minimizes the Negative Impact of Current Anticancer Chemotherapy on Nonmalignant Cells
The relative success of platinum (Pt)-based chemotherapycomes at the cost of severe adverse side effects and is associated with a highrisk of pro-oncogenic activation in the tumor microenvironment. Here, wereport the ...
Cyclometallated Imides as Templates for the H-Bond Directed Iridium-Catalyzed Asymmetric Hydrogenation of N-Methyl, N-Alkyl and N-Aryl Imines.
A combined computational and experimental approach allowed us to develop overall the most selective catalyst for the direct hydrogenation of N-methyl, N-alkyl and N-aryl imines described to date. Iridium catalysts with a ...
Behaviour of Pt/TiO2 catalysts with different morphological and structural characteristics in the photocatalytic conversion of ethanol aqueous solutions
Pt/TiO2 catalysts with a similar Pt dispersion and different morphological and structural characteristics were prepared, characterized and used in the photocatalytic transformation of aqueous ethanol solutions at room ...
