On the Ability of Bismuth to Couple Weakly Coordinating Anions
Angewandte Chemie International Edition, EarlyView.Motivated by the growing number of catalytic processes based on high‐valent Bi, we investigated in silico the reductive elimination step responsible for the coupling of weakly coordinating anions. Relativistic contributions appeared to be decisive to the electronic description of the intermediates involved in this process.

Chemistry – A European Journal, EarlyView.Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

Reduction of boron diffusion in silicon-germanium by fluorine implantation
, 2004 This paper investigates the effect of a 185 keV, 2.3×1015cm-2 F+ implant on boron thermal diffusion and boron transient enhanced diffusion (TED) in SiGe by characterising the diffusion of a boron marker layer in samples with and without a 288 keV, 6 ...

Multigramme synthesis and asymmetric dihydroxylation of a 4-fluorobut-2E-enoate
Beilstein Journal of Organic Chemistry, 2013 Esters of crotonic acid were brominated on a multigramme scale using a free radical procedure. A phase transfer catalysed fluorination transformed these species to the 4-fluorobut-2E-enoates reproducibly and at scale (48–53%, ca. 300 mmol).

Chemistry – A European Journal, EarlyView.Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.

The Diarylprolinol Silyl Ethers: After 20 Years Still Opening New Doors in Asymmetric Catalysis
Angewandte Chemie, Volume 138, Issue 11, 9 March 2026.Catalysis Rules! The year 2025 marks the 20th anniversary of diarylprolinol silyl ethers in asymmetric organocatalysis. During the first decade after their discovery, these catalysts have been established as one of the most versatile tools in aminocatalysis. Although now considered mature, recent years have witnessed renewed innovation.

Crystal structure landscape of conformationally flexible organo-fluorine compounds
CrystEngComm, 2016 The crystal structure landscape of an unsubstituted benzanilide was generated and a number of hypothetical structures were accessed with experimentally obtained crystal structures of mono-, di-, tetra- and penta-fluorobenzanilides.

Nickel‐Catalyzed Reductive Cross‐Coupling of Xanthate Esters With Aryl and Alkenyl Iodides
Chemistry – A European Journal, EarlyView.A nickel‐catalyzed reductive cross‐coupling of xanthate esters and aryl/alkenyl iodides is reported without the need for separate activators for the xanthate esters. The reaction utilizes a relatively low catalyst loading. Diarylmethanes with a good functional group variety can thus be synthesized indirectly from the corresponding benzylic alcohols ...
