Direct CO2 Capture and Reduction to High-End Chemicals with Tetraalkylammonium Borohydrides

Andreas Züttel, Kun Zhao, Loris Giovanni Lombardo, Heena Yang, Youngdon Ko

We demonstrate the ability of tetraalkylammonium borohydrides to capture large amounts of CO2, even at low CO2 concentrations, and reduce it to formate under ambient conditions. These materials show CO2 absorption capacities up to 30 mmolCO2 g(-1) at room ...

Investigation and modeling of odors release from membrane holes on daily overlay in a landfill and its impact on landfill odor control

Sami Rtimi

In the present work, we studied the NH(3)and H2S odor fluxes between the exposed working area and the HDPE covering film holes of the daily overlay in an actual landfill site with a daily operating area of 1600 m(2)in Hangzhou, China. We showed that the od ...

MoleculARweb: A Web Site for Chemistry and Structural Biology Education through Interactive Augmented Reality out of the Box in Commodity Devices

Matteo Dal Peraro, Luciano Andres Abriata, Lucien Fabrice Krapp, Fabio Jose Cortes Rodriguez

Augmented/virtual realities (ARs/VRs) promise to revolutionize STEM education. However, most easy-to-use tools are limited to static visualizations, which limits the approachable content, whereas more interactive and dynamic alternatives require costly har ...

Metal-Free Electrophilic Alkynylation of Sulfenate Anions with Ethynylbenziodoxolone Reagents

Jérôme Waser, Stefano Nicolai, Franck Le Vaillant, Stephanie Grace Elizabeth Amos, Alec Gagnebin

Alkynyl sulfoxides are important building blocks with a unique reactivity in organic chemistry, but only a few reliable methods have been reported to synthesize them. A novel route to access alkynyl sulfoxides is reported herein by using ethynyl benziodoxo ...

Ligand-Controlled Regiodivergent Hydroalkylation of Pyrrolines

Xile Hu, Deyun Qian

Nickel hydride (NiH) catalyzed hydrocarbonation has emerged as an efficient approach to construct new C-C bonds containing at least one C(sp(3)) center. However, the regioselectivity of this reaction is by far dictated by substrates. Described here is a st ...

One-Pot Synthesis of 1-[(Triisopropylsilyl)ethynyl]-1,2-benziodoxol-3(1H)-one (TIPS-EBX): Process Safety Assessment and Impact of Impurities on Product Stability

Jérôme Waser, Stefano Nicolai, Paola Caramenti, Durga Prasada Rao Hari, Lionel Schouwey, Miyeon Chang

The hypervalent iodine reagent 1-[(TriIsoPropylSilyl)Ethynyl]-1,2-BenziodoXol-3(1H)-one (TIPS-EBX) is among the most useful electrophilic and somophilic alkynylation reagents. Herein, we report a new synthetic protocol to access this reagent in one step fr ...

Metal-Organic Frameworks Invert Molecular Reactivity: Lewis Acidic Phosphonium Zwitterions Catalyze the Aldol-Tishchenko Reaction

Xiangru Xu, Berend Smit, Daniele Ongari, Gerald Bauer, Davide Tiana

The influence of metal-organic frameworks (MOFs) as additives is herein described for the reaction of n-alkyl aldehydes in the presence of methylvinylketone and triphenylphosphine. In the absence of a MOF, the expected Morita-Baylis-Hillman product, a beta ...

Novel Applications of Nitrous Oxide and Transition Metals for C-C and C-N Bond Formation

Gregor Kiefer

This thesis describes novel methods for and investigations into C–C and C–N bond formation reactions. Chapter 1 gives a very brief overview of established strategies for the formation of new C–C bonds in organic synthesis. In chapter 2, a multi‐step one‐po ...

Gold-Catalyzed Alkynylation: Acetylene-Transfer instead of Functionalization

Jérôme Waser, Jonathan Brand, Yifan Li

Over the last fifteen years, gold has been raised from the status of an inert noble metal to one of the most-often-used catalysts in synthetic chemistry. The functionalization of the triple bond of alkynes has been especially successful in this respect. In ...
