Arylative Ring Expansion of 3-Vinylazetidin-3-Ols and 3-Vinyloxetan-3-Ols to Dihydrofurans by Dual Palladium and Acid Catalysis

Qian Wang, Jieping Zhu, Takuji Fujii

In contrast to the well-studied 1-vinylcyclobutanols, the reactivity of 3-vinylazetidin-3-ols 1 and 3-vinyloxetan-3-ols 2 under transition metal catalysis remains largely unexplored. We report herein their unique reactivity under dual palladium and acid ca ...

Electrolyte engineering via ether solvent fluorination for developing stable non-aqueous lithium metal batteries

Mounir Driss Mensi, Yubo Zhao

Fluorination of solvents, useful for non-aqueous lithium-based batteries, improves the electrochemical stability but decreases the ionic conductivity. Here, the authors report a targeted functionalization of an ether solvent to balance the electrolyte ioni ...

Nitrous oxide as a diazo transfer reagent: the synthesis of triazolopyridines

Kay Severin, Farzaneh Fadaei Tirani, Iris Roswitha Landman

Nitrous oxide is a potential diazo transfer reagent, but its applications in organic chemistry are scarce. Here, we show that triazolopyridines and triazoloquinolines are formed in the reactions of metallated 2-alkylpyridines or 2-alkylquinolines with N2O. ...

Alkynyl triazenes enable divergent syntheses of 2-pyrones

Kay Severin, Nicolai Cramer, Carl Thomas Bormann, Jin Fay Tan

The 2-pyrone motif occurs frequently in bioactive natural products and is appreciated as synthetic intermediates. However, only few methods allow for diversifying functional group modifications on this relevant heterocycle. The distinct properties of 1-alk ...

Nanocapillary confinement of imidazolium based ionic liquids

Aleksandra Radenovic, Sanjin Marion, Sebastian James Davis, Zeng-Qiang Wu

Room temperature ionic liquids are salts which are molten at or around room temperature without any added solvent or solution. In bulk they exhibit glass like dependence of conductivity with temperature as well as coupling of structural and transport prope ...

Divergent Synthesis of Densely Substituted Arenes and Pyridines via Cyclotrimerization Reactions of Alkynyl Triazenes

Kay Severin, Nicolai Cramer, Carl Thomas Bormann, Florian Gérald Abela, Jin Fay Tan, Frederick Mark Chadwick

Densely substituted fused aromatic triazenes can be prepared by [2 + 2 + 2] cyclotrimerization reactions of 1-alkynyl triazenes. The Cp*Ru-catalyzed cyclization proceeds well with both simple alkynyl triazenes and tethered 1-diynyl triazenes. Attractively, ...

Auto-passivation of crystal defects in hybrid imidazolium/methylammonium lead iodide films by fumigation with methylamine affords high efficiency perovskite solar cells

Mohammad Khaja Nazeeruddin, Yi Zhang, Paul Joseph Dyson, Rosario Scopelliti, Zhaofu Fei, Farzaneh Fadaei Tirani, Emad Oveisi, Giulia Grancini, Xuehui Liu, Erfan Shirzadi

Hybrid perovskite solar cells have attracted tremendous interest in the photovoltaic community. Despite their high defect tolerance, reducing the trap density by material engineering and surface modification is still critical to further boost performance. ...

Photoelectrocatalytic arene C–H amination

Xile Hu, Lei Zhang, Jingshan Luo, Dan Ren, Laurent Liardet

Photoelectrochemical cells are widely studied for solar energy conversion. However, they have rarely been used for the synthesis of high added-value organic molecules. Here we describe a strategy to use haematite, an abundant and robust photoanode, for non ...
