Abstract

The article "Notes from Chemistry" covers various topics, including the application of machine learning at the TDDFT level for determining singlet and triplet excitation energies in a molecular database. It also reports on the structural changes of a germapyramidal compound during redox processes and the detection of microplastics using infrared spectroscopy. A new method for determining isotope ratios in spent nuclear fuel is presented. Other topics include the deuteration of aromatics, the reduction of benzoic acids to methylbenzenes, and the production of complex quasicrystal structures. It also reports on the light-induced inverse vulcanization of sulfur and the synthesis of a bifunctional ligand. The Krossing research group has shown how the nickel(I) complex [Ni(C6H6)2] is formed from [Ni(CO)4][F{Al(ORF)3}2]. Microextraction with magnetic ionic liquids and a multimethod for the analysis of polar metabolites are also discussed. Enzymes from cocaine biosynthesis could be used for drug development, and new terpenes from bacteria inhibit the replication of Sars-CoV-2. A new synthesis protocol enables the production of arylmanganese compounds, and an in-operando study allows for the direct measurement of reaction temperature in heterogeneous catalysis. Pyridines can be selectively meta-substituted.
