Deoxygenative trifluoromethylthiolation of carboxylic acids

Xile Hu, Runze Mao, Srikrishna Bera, Alexis Baptiste Cheseaux

Here we describe a deoxygenative trifluoromethylthiolation method that yields trifluoromethyl thioesters from readily available carboxylic acids. The method is built upon an "umpolung" strategy where triphenylphosphine is used to first activate an electrop ...

Equilibrium and Out-of-Equilibrium Adherence of Hydrogels against Polymer Brushes

Jennifer Mary Adrienne Alice Macron, Costantino Creton

At low pH, underwater adherence between poly(N,N-dimethylacrylamide) hydrogels and poly(acrylic acid) brushes is due to the formation of multiple hydrogen bonds. The effect of the key parameters controlling the formation of these interactions (contact time ...

Copper-catalyzed methylative difunctionalization of alkenes

Qian Wang, Jieping Zhu, Xu Bao, Minh Tu Ha, Takayuki Yokoe

Trifluoromethylative difunctionalization and hydrofunctionalization of unactivated alkenes have been developed into powerful synthetic methodologies. On the other hand, methylative difunctionalization of olefins remains an unexplored research field. We rep ...

Amorphous CaCO3: Influence of the Formation Time on Its Degree of Hydration and Stability

Francesco Stellacci, Esther Amstad, Camelia Borca, Huachuan Du, Mathias Steinacher, Anna Murello

Calcium carbonate (CaCO3) is one of the most abundant biominerals that is prevalent in rocks and often used as a structural material in marine animals. Many of these natural CaCO3-based materials display excellent mechanical properties that are difficult t ...

Cross-Coupling of Alkyl Redox-Active Esters with Benzophenone Imines: Tandem Photoredox and Copper Catalysis

Xile Hu, Runze Mao, Jonathan Balon

Alkyl amines are an important class of organic compounds in medicinal and materials chemistry. Until now very have been very few methods for the synthesis of alkyl amines by metal‐catalyzed cross‐coupling of alkyl electrophiles with nitrogen nucleophiles. ...

Selectivity control during the single-step conversion of aliphatic carboxylic acids to linear olefins

Jeremy Luterbacher, Florent Emmanuel Héroguel, Jher Hau Yeap, Bartosz Rozmyslowicz

We have studied the single-step catalytic conversion of biomass-derived aliphatic carboxylic acids to linear olefins via tandem hydrogenation/dehydration reactions. Hexanoic acid was converted to a mixture of hexenes (92.0% selectivity) over silica–alumina ...

Carboxylic Acid Functionalized Clathrochelate Complexes: Large, Robust, and Easy-to-Access Metalloligands

Rosario Scopelliti, Kay Severin, Kurt Schenk, Philip Pattison, Euro Solari, Mathieu Jérémie Marmier, Matthew David Wise

Polycarboxylate ligands are among the most important building blocks for the synthesis of metal–organic frameworks (MOFs). The ability to access these ligands in an efficient way is of key importance for future applications of MOFs. Here, we demonstrate th ...

Synergistic effect of carboxylic and amine ligands on the synthesis of CdSe nanocrystals

Martinus Gijs, Virendra Kumar Parashar

We demonstrate the drastic improvement in absorbance and photoluminescence (UV-PL) of CdSe nanocrystals (NCs) upon adding both a carboxylic acid and an amine ligand to the cadmium acetate green chemistry source. We combined carboxylate complexes of lauric ...

Ultrafast All-Polymer Electrically Tunable Silicone Lenses

Herbert Shea, Samuel Rosset, Luc Maffli, Michele Ghilardi

Dielectric elastomer actuators (DEA) are smart lightweight flexible materials integrating actuation, sensing, and structural functions. The field of DEAs has been progressing rapidly, with actuation strains of over 300% reported, and many application conce ...
