Rh(I)-Catalyzed Hydroamidation of Olefins via Selective Activation of N–H Bonds in Aliphatic Amines

Gabor Laurenczy, Yuehui Li, Matthias Beller

Hydroamidation of olefins constitutes an ideal, atom-efficient method to prepare carboxylic amides from easily available olefins, CO, and amines. So far, aliphatic amines are not suitable for these transformations. Here, we present a ligand- and additive-f ...

Ligand-Controlled Regiodivergent Pathways of Rhodium(III)-Catalyzed Dihydroisoquinolone Synthesis: Experimental and Computational Studies of Different Cyclopentadienyl Ligands

Nicolai Cramer, Matthew Wodrich, Jérôme Florian Gonthier, Baihua Ye

Rh-III-catalyzed directed C-H functionalizations of arylhydroxamates have become a valuable synthetic tool. To date, the regioselectivity of the insertion of the unsaturated acceptor into the common cyclometalated intermediate was dependent solely on intri ...

Exfoliation of layered double hydroxides for enhanced oxygen evolution catalysis

Xile Hu, Fang Song

The oxygen evolution reaction is a key reaction in water splitting. The common approach in the development of oxygen evolution catalysts is to search for catalytic materials with new and optimized chemical compositions and structures. Here we report an ort ...

Aqueous Oxidation of Sulfonamide Antibiotics: Aromatic Nucleophilic Substitution of an Aniline Radical Cation

Jeremy Samuel Arey, Peter Rudolf Tentscher

Sulfonamide antibiotics are an important class of organic micropollutants in the aquatic environment. For several, sulfur dioxide extrusion products have been previously reported upon photochemical or dark oxidation. Using quantum chemical modeling calcula ...

Diamine Bis(phenolate) as Supporting Ligands in Organoactinide(IV) Chemistry. Synthesis, Structural Characterization, and Reactivity of Stable Dialkyl Derivatives

Marinella Mazzanti

The homoleptic compounds [U(salan-R2)2] (R = Me (1), tBu (2)) were prepared in high yield by salt-metathesis reactions between UI4(L)2 (L = Et2O, PhCN) and 2 equiv of [K2(salan-R2)] in THF. In contrast, the reaction of the tetradentate ligands salan-R2 wit ...

Flexprint substrate enzyme sensor for determination of daily glucose-profiles for diabetic patients

Nico de Rooij, Peter Van der Wal

The goal is to develop a miniaturized system allowing continuous measurement of glucose concentration profiles over 24 hours for several days. The unique feature of the PharmaSens / IMT approach lies in the insertion mechanism and the needle size to assure ...

Structure of Zirconocene Complexes Relevant for Olefin Catalysis: Infrared Fingerprint of the Zr(C5H5)(2)(OH)(CH3CN)(+) Cation in the Gas Phase

Ulrich Lorenz

Cationic zirconocene complexes are active species in Ziegler-Natta catalysis for olefin polymerization. structure and metal-ligand bond strength strongly influence their activity. In the present work, the multiphoton dissociation (IRMPD) spectrum of mass s ...

The biphenyl-monitored effective size of unsaturated functional or fluorinated ortho substituents

The size of a series of typical substituents has been probed by dynamic NMR measurements of the barriers to aryl-aryl rotation of the corresponding biphenyls. The resulting B values are meaningful because only mono-ortho substituted compounds were investig ...

Novel Ruthenium Complexes with Sterically Demanding Cyclopentadienyl Ligands

Barnali Dutta

Investigations of ruthenium halfsandwich complexes have mostly focused on Cp and Cp* based derivatives due to the availability of easily accessible starting materials. However, it is interesting to have complexes with substituted cyclopentadienyl ligands i ...

Reactions of Alkynes with [RuCl(cyclopentadienyl)] Complexes: The Important First Steps

Rosario Scopelliti, Ursula Röthlisberger, Kay Severin, Euro Solari, Basile Curchod, Pablo Campomanes Ramos, Barnali Dutta

Cyclopentadienyl-ruthenium half-sandwich complexes with 2-bound alkyne ligands have been suggested as catalytic intermediates in the early stages of Ru-catalyzed reactions with alkynes. We show that electronically unsaturated complexes of the formula [RuCl ...
