Abstract The entitled reaction proceeds via a 1,3‐dipolar cycloaddition reaction of imines into aryl nitrile oxides.

Abstract Reductive cyclization of 2‐nitro‐benzamidines (I) and (III) affords title compounds (II) and (IV), resp., in moderate to high yields.

Abstract A variety of chalcone derivatives are synthesized via aldol condensation of diverse aldehydes with acyclic and cyclic ketones, under mild reaction conditions.

Abstract The garnet‐type solid‐state electrolyte Li6.85La2.9Ca0.1Zr1.75 Nb0.25O12 is prepared by calcination of LiOH, La2O3, CaCO3, ZrO2, and Nb2O5 in air (900 °C, 10 h) followed by pelletizing and further annealing at 1050 °C (12 h).

Abstract Using 2‐iodobenzoic acid as common starting material, two 2‐benzazepin‐1‐one derivatives (VIII) and (XII) are prepared.

Abstract A total synthesis of decarestrictine J is accomplished in a divergent way starting from commercially available materials.

Treatment of dialkylbenzylsilanes (1) with trityl tetrakis(pentafluorophenyl)borate (TPFPB) afforded the corresponding silylium ions in equilibrium with their intra- or intermolecular π-complexes, which underwent dehydrogenative annulation with various alkenes to form 1,2,3,4-tetrahydro-2-silanaphthalenes (4) in up to 82% isolated yield. Sterically bulkier substituents on the silicon atom tended to increase the yield of cyclic products 4. The annulation products retained the stereochemistry in cases of the reactions using internal alkenes. The use of diisopropyl(1-naphthyl)silane (2) instead of 1 also resulted in annulation to obtain the 2,3-dihydro-1-sila-1H-phenalene derivatives 6. Electrophilic aromatic substitution at the 8-position was predominant, despite the two potentially reactive positions on the naphthyl group. The steric hindrance of the naphthyl group prevented addition of the cis-alkene to the silylium ion, which would considerably decrease yields of the desired products from 2 compared to t...

Abstract Partially fluorinated triazoles are prepared through anodic fluorination of alkynes possessing an arylthio group and subsequent Cu(I)‐catalyzed azide‐alkyne cycloaddition with benzyl azide.
