Solvent- and catalyst-free reduction of CO2 with ammonia borane
Andreas Züttel, Youngdon Ko, Liping Zhong
Ammonia borane (AB) has been extensively studied as a solid-state hydrogen storage material. On the other hand, its reactivity with CO2 is still unclear, especially in the solid state. By carefully controlling the CO2 pressure and temperature, AB efficient ...
Cambridge2024From defect to effect: controlling electronic transport in chevron graphene nanoribbons
Oleg Yazyev, Kristians Cernevics
While bottom-up synthesis allows for precise control over the properties of graphene nanoribbons (GNRs), the use of certain precursor molecules can result in edge defects, such as missing benzene rings that resemble a 'bite'. We investigate the adverse eff ...
IOP Publishing Ltd2023The Photoisomerization Pathway(s) of Push‐Pull Phenylazoheteroarenes
Anne-Clémence Corminboeuf, Sergio Vela Llausi
Azoheteroarenes are the most recent derivatives targeted to further improve the properties of azo‐based photoswitches. Their light‐induced mechanism for trans‐cis isomerization is assumed to be very similar to that of the parent azobenzene. As such, they i ...
2020Methanol production from CO(2)via an integrated, formamide-assisted approach
Paul Joseph Dyson, Andreas Züttel, Jorge Gustavo Uranga, Aswin Gopakumar, Gabriela Gastelu, Tim Pfister, Gunay Imanzade
The synthesis of fuels from CO2 has made tremendous progress in recent years, although practical applications remain limited. Herein, we describe a cyclic process that produces MeOH from CO(2)via formamide intermediates, which are initially reduced using N ...
ROYAL SOC CHEMISTRY2020Synthetic Studies toward Amanita Phalloides Toxins
Philipp Georg Werner Seeberger
Amatoxins are ribosomally synthesized and post-translationally modified bicyclic octapeptides biosynthesized by the deadly basidiomycete fungus Amanita phalloides. Amongst this group, alpha-amanitin is the most widely known toxin and is currently under inv ...
EPFL2020New insights into the effect of nitrogen incorporation in Mo: catalytic hydrogenation vs. hydrogenolysis
Lioubov Kiwi, Fernando Cardenas Lizana, Daniel André Samuel Lamey
The catalytic effect of nitrogen incorporation into Mo on hydrogenation (of -NO2 to -NH2 in nitrobenzene to aniline) and hydrogenolysis (of -C?O in benzaldehyde to toluene) processes has been assessed. Bulk Mo was prepared by temperature programmed reducti ...
ROYAL SOC CHEMISTRY2019The dilemma between acid and base catalysis in the synthesis of benzimidazole from o-phenylenediamine and carbon dioxide
Paul Joseph Dyson, Simon Nussbaum, Martin Hulla, Alexy Robert Bonnin
The tandem synthesis of benzimidazole and other azoles can be achived by the N-formylation of ortho-substituted anilines followed by a cyclization reaction. However, CO2-based N-formylations with hydrosilane reducing agents are base catalyzed whereas the c ...
2019Molecular engineering of enamine-based small organic compounds as hole-transporting materials for perovskite solar cells
Mohammad Khaja Nazeeruddin, Michael Saliba, Sanghyun Paek, Kyung Taek Cho
The search for new classes of hole transporting materials (HTMs) is a very important task on the way towards commercialization of perovskite solar cells (PSCs). In this work, the synthesis and performance in PSCs of new enamine-based HTMs are presented. Th ...
ROYAL SOC CHEMISTRY2019Metal-Organic-Framework-Derived Co3S4 Hollow Nanoboxes for the Selective Reduction of Nitroarenes
Wendy Lee Queen, Emad Oveisi, Daniel Teav Sun, Shuliang Yang, Li Peng, Safak Bulut
MOF-derived Co3S4/CN hollow nanoboxes (CN=nitrogen-doped carbon) was used to catalyze the chemoselective reduction of nitroarenes to anilines under mild reaction conditions with H-2 as the reducing agent. The catalyst provides high conversion efficiencies ...
2018Re-assessing the Formation of N-nitrosamines during Chloramination of Various Nitrogenous Compounds using Specific and Total N-nitrosamines Analysis
Urs von Gunten, Florian Frédéric Vincent Breider, Andrea Piazzoli
N-nitrosamines (NOAs) are potent carcinogenic and mutagenic compounds that can be present in water, biological fluids, food, consumer products and cigarette smoke. Several studies have shown that the formation of NOAs in water can arise from the reactions ...
