Regiodivergent and Enantioselective Synthesis of Cyclic Sulfones via Ligand-Controlled Nickel-Catalyzed Hydroalkylation

Cyclic sulfones have demonstrated important applications in drug discovery. However, the catalytic and enantioselective synthesis of chiral cyclic sulfones remains challenging. Herein, we develop nickel-catalyzed regiodivergent and enantioselective hydroal ...

Co-Adsorption of Alcohols and Water in JUK-8 Studied Using Quasi-Equilibrated Thermodesorption

Pattaraphon Rodlamul

JUK-8 ([Zn(oba)(pip)]n, oba2- = 4,4 '-oxybis(benzenedicarboxylate), pip = 4-pyridyl-functionalized benzene-1,3-dicarbohydrazide) is a hydrolytically stable flexible metal-organic framework. Owing to its unusual adsorptive properties, JUK-8 can be considere ...

Taming the radical cation intermediate enabled one-step access to structurally diverse lignans

Jieping Zhu, Cédric Fung, Qiang Wang, Jia-Chen Xiang

Lignans, in spite of their structural diversity, are all biosynthetically derived from coniferyl alcohol. We report herein a divergent synthesis of lignans from biomass-derived monolignols in a short synthetic sequence. Blue LED irradiation of a dichlorome ...

Unified divergent strategy towards the total synthesis of the three sub-classes of hasubanan alkaloids

Qian Wang, Jieping Zhu, Guang Li

Elegant asymmetric synthesis of hasubanan alkaloids have been developed over the past decades. However, a divergent approach leading to all three sub-classes of this family of natural products remains unknown. We report herein the realization of such an en ...

Development of remote C-H bond functionalization of redox-active alcohol derivatives and oxidative transformations under photoredox catalysis

Alexandre Julien Florent Leclair

The development of radical-based remote C(sp3)-H functionalizations of redox-active alcohol derivatives, oxidative cycloaddition and rearrangement transformations under visible light photocatalysis constitute the basis of this thesis.The first chapter desc ...

Radial Spin Texture of the Weyl Fermions in Chiral Tellurium

Majed Chergui, Henrik Moodysson Rønnow, Marco Grioni, Oleg Yazyev, Luc Testa, Daniel Gosalbez Martinez, Philippe Bugnon, Alberto Crepaldi, Luca Moreschini, Mauro Fanciulli, Simon Karl Moser, Gianmarco Gatti, Serhii Polishchuk

Trigonal tellurium, a small-gap semiconductor with pronounced magneto-electric and magneto-optical responses, is among the simplest realizations of a chiral crystal. We have studied by spin- and angle-resolved photoelectron spectroscopy its unconventional ...

Photochemical Functionalization of Heterocycles with EBX Reagents: C-H Alkynylation versus Deconstructive Ring Cleavage

Jérôme Waser, Marion Marie-Agnès Garreau

The development of novel methodologies for the functionalization of saturated heterocycles is highly desirable. Herein, we report a cheap and efficient photochemical method for the C-H functionalization of saturated O-heterocycles, as well as the deconstru ...

Inkjet‐Printed Composites for Room‐Temperature VOC Sensing: From Ink Formulation to Sensor Characterization

Jürgen Brugger, Thomas Maeder, Mohammadmahdi Kiaee

The authors report the fabrication and characterization of chemiresistive sensors, composed of a thermoplastic elastomer (TPE), styrene‐ethylene‐ran‐butylene‐styrene, and a high‐structure carbon black (CB) targeted for detecting hydrocarbons at or near roo ...

Emissions of volatile organic compounds from interior materials of vehicles

Dusan Licina, Shen Yang

People spend a substantial amount of daily time in vehicle environments being exposed to variety of airborne chemicals. High concentrations of volatile organic compounds (VOCs) inside vehicle cabins have been of increasing concern owing to various health r ...

Ozone concentration measured during the Arctic Ocean 2018 expedition

Julia Schmale, Andrea Baccarini

Ozone was measured with a 2B Technology ozone monitor (model 205). The concentration is reported as a mixing ratio in parts per billion [ppb], at 60 seconds average. Ozone is a trace gas that can be formed directly in the troposphere (the most important fo ...
