Reenvisioning the De Mayo Reaction: A Boron‐Enabled Cycloaddition Approach
Angewandte Chemie, EarlyView.An oxa‐boracycle conformational lock strategy enables photocatalytic [2+2] cycloaddition to afford densely substituted cyclobutylboronates. The conformational constraint suppresses triplet relaxation and promotes productive bimolecular reactivity.

Catalytic Functionalization of Unactivated π‐Bonds Enabled by Bidentate Directing Auxiliaries
Angewandte Chemie, EarlyView.This review explores how bidentate directing auxiliaries have advanced transition‐metal catalysis for unactivated alkene/alkyne functionalization. By leveraging chelated intermediates, bidentate directing auxiliaries enable precise hydrofunctionalization, difunctionalization, and C─H activation of π‐bonds with unique selectivity and reactivity.

Latin datives with prefixed verbs and beyond: A view from the theory of applicatives
Catalan Journal of Linguistics, 2017 I discuss the syntax and semantics of dative DPs with a spatial (Ground) interpretation, focusing on those dependent on prefixed verbs, in Early and Classical Latin.

Personal and impersonal sentences in Lithuanian and Proto-Indo-European
Vilnius University Open Series, 2022 The dative subject construction of the historical languages is the continuation of the Proto-Indo-European thematic present. It was largely replaced by the construction with a nominative subject that continued the athematic present as well as the aorist,

A methionine-lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase. [PDF]
FEBS LettThis study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

On the Ability of Bismuth to Couple Weakly Coordinating Anions
Angewandte Chemie, 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.

Ways of being a dative across Romance varieties [PDF]
, 2020 In this article, we argue that the term dative can correspond to objects of a very different linguistic nature, even in typologically close languages. Specifically, in syntactic terms datives can be different from accusatives or identical to them at some

1,7‐Digallatetracarborane: Between Nucleophilic closo‐Cluster and “Inverse Sandwich” Digallylene
Angewandte Chemie, EarlyView.A dianionic π‐ligand is used to make a Janus‐type twofold complex with low‐valent gallium Ga(+I). The resulting compound can be seen as and reveals the reactivity of both: a Wade‐type closo‐carborane cluster with nucleophilic Ga‐sites, as well as π‐ligand stabilized Ga(I) atoms in an inverse sandwich compound.

Anuario del Seminario de Filología Vasca "Julio de Urquijo", 2010 Under certain conditions, nonstandard varieties of Basque display so-called quirky dative objects, a phenomenon that belongs to the broader family of constructions studied in the typological literature as Differential Object Marking (DOM).
