Solution Synthesis of Actinide Chalcogenide and Oxychalcogenide Nanoparticles
Angewandte Chemie, EarlyView.We report the synthesis of UOS, UOSe, and US2 nanoparticles under colloidal conditions. The magnetic properties were measured of all three materials and compared to prior studies of UO2 nanoparticles. Nanoparticle phases were determined using powder diffraction, and size by transmission electron microscopy.

Cross metathesis of unsaturated epoxides for the synthesis of polyfunctional building blocks
Beilstein Journal of Organic Chemistry, 2015 The cross metathesis of 1,2-epoxy-5-hexene (1) with methyl acrylate and acrylonitrile was investigated as an entry to the synthesis of polyfunctional compounds.

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.

Concise Total Synthesis of (+)-Brefeldin A: A Combined β-Lactone/Cross-Metathesis-Based Strategy
, 2016 A highly convergent total synthesis of (+)-brefeldin A that relies on a diastereoselective, β-lactone-based cyclopentane synthesis combined with complex cross-metathesis reactions is described.

Heavier Alkyne‐Ni0 Complexes, [R2E2·Ni] (E = Sn, Pb), Exhibiting σ‐Complex Character
Angewandte Chemie, EarlyView.Using a reductive group elimination strategy, heavier alkyne (LEEL; E = Sn, Pb) complexes of Ni0 are accessed. In contrast to classical alkyne coordination, these systems are best described as σ‐complexes, driven by ligand‐induced constraints and the established poor π‐bonding in heavier alkyne analogues.

Light‐Driven Diselenide Metathesis in Peptides
ChemistryOpen, 2019 Peptides containing selenocysteine moieties are susceptible to non‐catalytic reactions of diselenide bonds metathesis induced by visible light. In contrast to previously reported radical metathesis of disulfide bridges in cysteine derivatives, this newly

Olefin cross metathesis and ring-closing metathesis in polymer chemistry [PDF]
Polymer Chemistry, 2017 The use of olefin cross metathesis in preparing functional polymers, through either pre-functionalisation of monomers or post-polymerisation functionalisation is growing in both scope and breadth, as discussed in this review article.

The synthesis of some new polymeric materials as potential additives for diesel fuel [PDF]
, 1993 Wax crystal formation in diesel and related hydrocarbon fuels during cold weather is a long standing problem. Current polymeric additives to diesel fuel modify the crystal habit of the wax, in a variety of ways, to improve its performance at low ...

Nucleophilic Gallyl Anions Enable Ga─Au Bimetallic Ammonia Activation
Angewandte Chemie, EarlyView.Unlocking gallyl nucleophiles: Counterion control enables formation of an unsupported gallyl─gold complex. Gold coordination induces a polarity switch at gallium, enabling cooperative activation of NH3 and related N─H/O─H substrates under mild conditions.
