Hochgradig enantioselektive Organokatalyse mit zweizähnigen Halogenbrückendonoren

Angewandte Chemie, EarlyView.
In einer Mukaiyama‐Aldol‐Modellreaktion mit allgemeinen Substraten wurden hohe Enantioselektivitäten mit einem modifizierbaren, bidentaten Iod(I)‐basierten Halogenbrücken‐Organokatalysator erreicht. Die entscheidende Rolle der Halogenbrücken wurde durch das schlechte Abschneiden des entsprechenden Wasserstoffbrückendonors und durch DFT‐Berechnungen ...

Hermite Calculus [PDF]

, 2017
We develop a new method of umbral nature to treat blocks of Her mite and of Hermite like poly- nomials as independent algebraic quantities. The Calculus we propose allows the formulation of a number of ”practical rules” allowing significant ...

Bevorzugte Alkan‐Komplexierung: Kristallisation eines kationischen Mangan(I)‐Pentan σ‐Komplexes aus der Lösung

Angewandte Chemie, EarlyView.
Oxidation von Mn2(CO)10 unter pseudo‐Gasphasenbedingungen generiert den schwach koordinierten 16‐Valenzelektronenkomplex [Mn(CO)5]+ als Intermediat, der n‐Pentan binden kann, da dieses der am stärksten bindende Ligand im System ist. Drei Isomere dieses Komplexes wurden mit Tieftemperatur‐NMR‐Spektroskopie und Einkristall‐Röntgenbeugung untersucht.

Varroa destructor detection on honey bees using hyperspectral imagery [PDF]

arXiv
Hyperspectral (HS) imagery in agriculture is becoming increasingly common. These images have the advantage of higher spectral resolution. Advanced spectral processing techniques are required to unlock the information potential in these HS images. The present paper introduces a method rooted in multivariate statistics designed to detect parasitic Varroa

Photo‐controlled Release of Urea Enables the Detection of Urea‐Urease Intermediates by cryo‐FTIR

Angewandte Chemie International Edition, Accepted Article.
Caged compounds are a valuable tool to photocontrol the release of enzymatic substrates in a reaction. For example, caged urea molecules were proposed to control urea delivery to urease reactions and aid the determination of the catalytic mechanism of this enzyme.

Hopf and Bautin bifurcations in a 3D model for pest leafhopper with stage structure and generalist predatory mite [PDF]

arXiv
In a recent paper of Yuan and Zhu (J. Differential Equations 321(2022) 99-129), the nature of dynamics of a generalist predator and prey with stage structure is modeled as a three-dimensional coupled nonlinear differential system. A detailed analysis of the bifurcation shows that the model exhibits a high complexity in its dynamics, which arises from ...
