Abstract:

AbstractThe control of tetrahedral carbon stereocentres remains a focus of modern synthetic chemistry and is enabled by their configurational stability. By contrast, trisubstituted nitrogen1, phosphorus2 and sulfur compounds3 undergo pyramidal inversion, a fundamental and well-recognized stereochemical phenomenon that is widely exploited4. However, the stereochemistry of oxonium ions—compounds bearing three substituents on a positively charged oxygen atom—is poorly developed and there are few applications of oxonium ions in synthesis beyond their existence as reactive intermediates5,6.

Abstract Tris[(triphenylphosphine)gold(I)]telluronium tetrafluoroborate (1) was prepared from the corresponding oxonium salt and bis(t-butyldimethylsilyl)tellurium in dichloromethane at -78°C.

In the crystal lattice, the cations form tellurium-capped triangles of gold, which are associated into dimers through short intermolecular Au -Au contacts, resembling those in the corresponding sulfur and selenium compound

Abstract:

Dichloroacetyl fluoride was investigated in the superacids HF/MF5 and DF/MF5 (M = As, Sb). The O‐hemiprotonated species of dichloroacetyl fluoride is formed in the binary superacidic systems HF/MF5 and DF/MF5 (M = As, Sb) as hexafluoridoarsenates and hexafluoridoantimonates. With an excess of the strong Lewis acid SbF5 dichloroacetyl fluoride reacts under the formation of the oxonium salt [CCl2HCF2OX2][SbF6] in the superacidic system XF/SbF5 (X = H, D) after HF‐ or DF‐addition, respectively. The colorless salts were characterized by low‐temperature vibrational spectroscopy, NMR spectroscopy, a

Abstract:

Pyrylium compounds are structures based on an oxonium heterocycle that has been extensively studied thanks to their superior absorption and fluorescence properties. In this study, pyrylium salts were first shown to be obtained in the solvent-free medium. Six pyrylium compounds, three of which were novel, were synthesized using this method. These compounds have different auxochromes on the phenyl groups at the 2,4 and 6 positions. In the final step, the photophysical properties of these compounds were examined and the effects of basic auxochromes on pyrylium photophysics were revealed.
