Mildly thermal air or HNO3 oxidized activated carbons catalyse oxidative dehydrogenative couplings of benzo[b]fused heteroaryl 2,2’‐dimers, e.g., 2‐(benzofuran‐2‐yl)‐1H‐indole, to chiral 3,3’‐coupled cyclooctatetraenes or carbazole

HNO3-oxidized carbon nanotubes catalyze oxidative dehydrogenative (ODH) carbon-carbon bond formation between electron-rich (hetero)aryls with O-2 as a terminal oxidant. The recyclable carbocatalytic method provides a convenient and an operationally e

A photoreductive protocol utilizing [Ru-(bpy)3]2+ photocatalyst, blue light LEDs, and ascorbic acid(AscH2) has been developed to reduce nitro N-heteroaryls to the corresponding anilines. Based on experimental and computational results and previous st

A simple "reagent-free" thermal air treatment turns active carbon into a mildly oxidized material with increased quinoidic content that catalytically dehydrogenates saturated N-heterocycles to the corresponding aromatic compounds. Thermal decarboxyla

Reaction mechanisms play an integral part in understanding chemical phenomena. Chemists use their knowledge of reaction mechanisms both when formulating research questions and when carrying out experiments in the fume hood or in silico. Accurate unde

Novel approach with amide-tethered H-bond donor NHC ligands enabled Au(I)-catalysis via H-bonding. The plain NHC-Au(I)-Cl complex catalysed conversions of terminal N-propynamides to oxazolines, and enyne cycloisomerization with an acid additive, in D

The gold-catalyzed 1,3-O-transposition of ynones occurs intermolecularly via a cyclic organo-gold acetal intermediate formed from the nucleophilic oxo attack of a second ynone, i.e. either starting material or product, on a gold-activated ynone. The
