Anion‐Controlled Structural Interconversion of Palladium Cages Enables Separations by Selective Guest Capture and Release

Angewandte Chemie, EarlyView.
We report a pair of interconvertible palladium(II) cages assembled from an asymmetric ligand, whose switching is triggered by specific counter‐anions, tetrafluoroborate (BF4−) and bis(trifluoromethanesulfonyl)imide (NTf2−). Their complementary guest preferences enable orthogonal, multi‐cycle catch‐and‐release, exemplified by the selective purification ...

An unusual case of methemoglobinemia resulting from self-administration of nitrobenzene in a psychiatric patient

MGM Journal of Medical Sciences, 2022
Nitrobenzene, when consumed in large enough doses, can cause methemoglobinemia. By reducing oxygen unloading and oxygen binding, methemoglobinemia reduces oxygen delivery.

Chemical Upcycling of Nitrile Butadiene Rubbers to Polyamines and Polyols by Chemoselective Catalytic Hydrogenation

Angewandte Chemie, EarlyView.
We demonstrate here the transformation of NBR (Nitrile butadiene rubber) including post‐consumer waste sourced from nitrile gloves and o‐rings into polyamines and polyols via ruthenium catalyzed hydrogenation. ABSTRACT We report here two new approaches for the chemical recycling/upcycling of nitrile butadiene rubber (NBR) to make either polyamines or ...

A Novel Reaction System for Cogeneration of Chemicals and Electric Energy by Electrochemical Reduction of Nitrobenzene with Iron

International Journal of Electrochemical Science, 2016
We report a novel green route for generate electric energy by simultaneously electrochemical reduction of nitrobenzene with iron which is carried out in a home-made diaphragm electrolytic cell using iron as reducer. The result shows that nitrobenzene can

Nitrobenzene poisoning presenting as Methemoglobinemia

Muller Journal of Medical Sciences and Research, 2014
Consumption of toxic compounds in an attempt to commit suicide is very common. Organophosphorus compounds are the most commonly consumed and fatal poisons. Nitrobenzene consumption for suicidal purposes is very rare.

Extraordinary sensitivity of the electronic structure and properties of single-walled carbon nanotubes to molecular charge-transfer

, 2008
Interaction of single-walled carbon nanotubes with electron donor and acceptor molecules causes significant changes in the electronic and Raman spectra, the relative proportion of the metallic species increasing on electron donation through molecular ...

Tuning the selectivity of nitrobenzene hydrogenation over Pd/CeO2 catalysts for azoxybenzene synthesis under solvent-free conditions

Catalysis Communications, 2023
Precise control of selectivity in nitrobenzene hydrogenation is a long-standing challenge, especially under solvent-free conditions. The PdOx is the key species for enhancing H2 dissociation and nitrobenzene conversion.
