Autoencoding Undirected Molecular Graphs With Neural Networks [PDF]
arXiv, 2019 Discrete structure rules for validating molecular structures are usually limited to fulfillment of the octet rule or similar simple deterministic heuristics. We propose a model, inspired by language modeling from natural language processing, with the ability to learn from a collection of undirected molecular graphs, enabling fitting of any underlying ...

Lewis Acid Properties of Tetrel Tetrafluorides—The Coincidence of the -Hole Concept with the QTAIM Approach [PDF]
, 2017 Tetrel bond is analysed for a series of ZF(4) (Z = C, Si, Ge) complexes with one and two NH3 or AsH3 ligands. The MP2/aug-cc-pVTZ calculations were performed and supported by results of the Quantum Theory of Atoms in Molecules (QTAIM) and the Natural ...

Indole Synthesis via Allenyl Ester; Enantioselective Total Synthesis of Geissoschizoline
ChemistryEurope, EarlyView.An indole synthesis via an allenyl ester intermediate at ambient temperature has been developed. The mild reaction conditions allow the use of a broad range of substrates. Notably, the utility of this approach is demonstrated through the asymmetric total synthesis of geissoschizoline, a Strychnos‐type monoterpenoid indole alkaloid.

Reduction of hypervalent iodine by coordination to iron(iii) and the crystal structures of PhIO and PhIO2 [PDF]
, 2016 Iodine L3-edge XANES spectra using reference compounds with formal iodine oxidation states spanning −1 to +7 show that iodine in an Fe(iii) coordinated iodosylbenzene (PhIO) is reduced compared to parent hypervalent PhIO which has been structurally ...

Chemistry – A European Journal, EarlyView.We discuss the developments in the light‐driven oxidation of alcohols with PC. We report cases where the homogeneous systems can be interfaced with electrochemical tools or adapted in flow and where the PC are integrated in sensitized materials. Abstract The oxidation of alcohols retains an enormous importance in industry and in synthetic organic ...
