1. The peculiarities of the properties of 3-hydroxyflavone are due to the fact that the introduction of the proton-donating hydroxy group directly into the heterocycle leads to an increase in the aromaticity of the pyrone fragment through the stabili

Vilsmeier formylation of 1,2-diphenylimidazo[1,2-a]benzimidazole leads to the 3-formyl derivative, while heating with acetic anhydride in sulfuric acid gives the 3-acetyl derivative. The nitration of this benzimidazole with potassium nitrate in sulfu

The effect of various physical processes on the replicability of cells for a quantum frequency standard based on Rb87 was investigated. A replication accuracy of 2 · 10−11 was obtained experimentally for the frequency of the spectral line of the g
