Sustainable Access to N‐Heterocycles: One‐Pot Cascade Synthesis of Pyrroles From Bio‐Derived Furans

Angewandte Chemie, EarlyView.
Highly dispersed platinum (Pt) clusters on Brønsted acid‐rich HY zeolite enable a one‐pot cascade conversion of bio‐derived furans and nitroarenes into pyrroles. Highly dispersed Pt sites ensure selective nitro hydrogenation, while Pt nanoparticles promote undesired over‐hydrogenation.

Dopant‐Tailored Matrices: A Crystal Engineering Strategy for Organic Room‐Temperature Phosphorescent Host–Guest Systems and Beyond

Angewandte Chemie, EarlyView.
Rather than selecting dopants to match a pre‐existing host matrix, the dopant‐tailored matrix strategy involves rational engineering of host matrices around a preselected class of dopants by targeting matrix packing motifs that promote synergistic host‐dopant interactions upon doping.

Influence of electrochemically prepared poly(pyrrole-co-N-methyl pyrrole) and poly(pyrrole)/poly(N-methyl pyrrole) composites on corrosion behavior of copper in acidic medium

, 2013
Poly(pyrrole-co-N-methyl pyrrole) copolymer and poly(pyrrole)/poly(N-methyl pyrrole) bilayer composites were electrochemically synthesized on copper by cyclic voltammetry from aqueous solution of 0.3 M oxalic acid and 0.1 M monomer.

A Modular Synthesis of C5‐Sulfenyl Thiazoles via an Intermolecular Pummerer Rearrangement: An Underexplored Scaffold for Medicinal Chemistry

Angewandte Chemie, EarlyView.
Modular access to underexplored C5‐sulfenyl thiazoles via an intermolecular Pummerer rearrangement is reported. The methodology exhibits a broad functional group tolerance enabling the seamless design of trisubstituted thiazole cores bearing a sulfur handle for further elaboration.

Nitrogen Radical Photocatalysed Reduction of Nitrous Oxide

Angewandte Chemie, EarlyView.
This work offers the first example of reduction of the potent greenhouse gas N2O to the benign products N2 and O(Bpin)2 using a nitrogen‐based catalyst. The active catalyst is shown to be a nitrogen‐based radical which operates under photocatalytic conditions.

Ruthenium‐Catalyzed Nitrile‐Acrylate Reductive Coupling by 2‐Propanol: Synthesis of Enantioenriched β‐Amino Esters

Angewandte Chemie, EarlyView.
The first nitrile reductive couplings beyond stoichiometric metals or metalloids are described. Using a ruthenium catalyst derived from RuHCl(CO)(PPh3)3 and Cy‐BIPHEP, 2‐propanol‐mediated reductive coupling of phenyl acrylate with aromatic or aliphatic nitriles delivers α,β‐unsaturated β‐amino esters.

Novel 1H-Pyrrole-2,5-dione (maleimide) proxies for the assessment of photic zone euxinia

, 2015
1H-Pyrrole-2,5-diones (maleimides) and 1-alkyl-2,3,6-trimethylbenzenes (aryl isoprenoids), degradation products of tetrapyrrole pigments and carotenoids respectively, were analysed and compared with pristane/phytane (Pr/Ph) ratios to reconstruct past ...

Katalytischer Schwefelatomtransfer vermittelt durch einen Bis(disulfido)‐Titankomplex

Angewandte Chemie, EarlyView.
Mehrelektronentransformationen mit Titan sind aufgrund der limitierten Zugänglichkeit niedervalenter Vorstufen bislang nur unzureichend untersucht. Die Vier‐Elektronen‐Aktivierung von elementarem Schwefel durch einen Ti(IV)‐Komplex führt zu einem seltenen Bis(disulfido)‐Titankomplex, der die effiziente katalytische Synthese von Isothiocyanaten aus ...
