Synthesis of 16‐Electron RuHCl(CO)(PPh3)2 Catalyst Rendering Superior C=C Double Bond Isomerization Activity

ChemCatChem, Accepted Article.
The double bond isomerization of olefins is an atomic‐efficient, industrially highly relevant chemical reaction. One of its emerging applications is the tandem isomerization metathesis (ethenolysis) reaction (ISOMET or IE) used for transforming plastic waste to propylene.

Understanding identity processes in support for reactionary and progressive social movements among advantaged and disadvantaged groups: The role of collective narcissism and secure ingroup identity

European Journal of Social Psychology, Volume 52, Issue 7, Page 1047-1063, December 2022., 2022
Abstract Across five studies (two representative, one pre‐registered, total N = 4962), we examined the role of collective narcissism and secure identity in support for reactionary (Alt‐Right and nationalist) and progressive (Black Lives Matter and Women's Strike) social movements among advantaged (White Americans and Polish national majority) versus ...

A Biocatalytic Cascade for the Valorisation of Sugars.

ChemCatChem, Accepted Article.
Biocatalytic cascades offer products of multistep synthesis without the use of protecting groups or isolation of intermediates. This strategy is particularly amenable to the synthesis of iminosugars, where traditional routes typically suffer from lengthy and inefficient steps.

How opposing ideological groups use online interactions to justify and mobilise collective action

European Journal of Social Psychology, Volume 52, Issue 7, Page 1082-1110, December 2022., 2022
Abstract The purpose of this pre‐registered study was to investigate how different ideological groups justified and mobilised collective action online. We collected 6878 posts from the social media accounts of pro‐Black Lives Matter (n = 13) and anti‐Black Lives Matter (n = 9) groups who promoted collective action in the month after George Floyd's ...

Catalytic Silylation of Alkynyl C(sp)–H bonds with tert‐Butyl‐Substituted Silyldiazenes

ChemCatChem, Accepted Article.
The deprotonative silylation of terminal alkynes constitutes one of the most privileged strategies to prepare alkynylsilanes owing to the relatively high acidity of C(sp)–H bonds. While the key deprotonation step is usually mediated by stoichiometric amounts of strong Brønsted bases (e.g.

Advances in electrochemical detection methods for measuring contaminants of emerging concerns

Electrochemical Science Advances, Volume 2, Issue 6, December 2022., 2022
Abstract The presence of contaminants of emerging concerns (CECs) such as pharmaceuticals and personal care products, endocrine disrupting compounds (EDCs), per/poly‐fluorinated substances (PFAS), pesticides, and nanomaterials poses significant challenges to the environment and human health.
