“…Even the content of substances in extremely small amounts leads to changes in the physical-chemical properties and biological activity of such water [8][9][10][11]. In addition, there is research which confirms that ultra-high dilutions of substances are systems different from both water used as a solvent and similarly prepared water dilutions [12]. In particular, such systems are characterized by structuredness associated with the formation of special diverse heterogeneities: nanoassociates, nanobubbles, bubstons, water domains or submillimeter density inhomogeneities [5,[13][14][15][16][17].…”

This paper investigates the effects of europium acetate and intensive stirring on the intermolecular properties of water in solutions. To do this, we studied aqueous solutions of europium acetate in a wide range of concentrations, which were prepared by serial dilution using a microfluidic unit. Water and similarly prepared water dilutions were used as controls. Raman spectroscopy and infrared (IR) spectroscopy were applied to assess the features of hydrogen bonds formed in the studied solutions. Using Raman spectroscopy, it was shown that intermolecular binding is stronger in solutions of europium acetate of 10–1 M and 10–3 M than in water controls. On the contrary, solutions of europium acetate at a concentration of 10–10 М and some lower concentrations demonstrate weaker hydrogen bonding than in the respective water dilutions, which was shown by both methods. Such differences were observed even in solutions with a calculated concentration of europium acetate below 10–24 M. When comparing water with control dilutions of water, it was established that intermolecular binding is different (stronger or weaker) in high dilutions of water than in water not subjected to the dilution procedure. This indicates that the dilution process itself significantly influences the properties of water in solutions. Additionally, the paper discusses the energy state of water molecules in the studied solutions.

Aqueous solutions and other polar liquids, perturbed by serial dilutions and vigorous shaking, have properties which are of importance for toxicology, medicine and wastewater treatment. Extensive research has shown that for serially diluted polar liquids, e.g., water, alcohol and their solutions, vigorous shaking after each dilution step may alter their structure, physicochemical characteristics and bioactivity. The alterations may occur when the concentrations of the liquids drop below a solute dependent threshold concentration. Typically, the threshold concentrations are in the 10 -6 -10 -10 mol / liter range. In the current study, the ultraviolet absorption and emission spectra of such liquids are analyzed. The analyses are carried out within the context of quantum electrodynamics (QED). The analyses show that the spectra can be consistently explained by the QED model for serially diluted vigorously shaken polar liquids, developed by Yinnon and Yinnon [Int J Mod Phys B 25:3707-3743 (2011)].

“…The progress in the chemistry of 5-thioxohexahydroimidazo [4,5-d]imidazol-2(1H)-ones (monothioanalogues of glycolurils) is of great interest due to various practically useful properties of both glycolurils [1][2][3][4] and their iminoand thioanalogues. [5][6][7][8][9][10][11][12][13][14][15] Thioanalogues of glycolurils have already been recognized as substrates for the template-directed crossed-Claisen condensation, [8][9][10][11] building blocks for the synthesis of semithiobambusurils, 12 organocatalysts for N-Boc protection of amines 13 or α-monobromination of 1,3-dicarbonyl compounds, 14 and as anxiolytic agents.…”

Simple approach to the synthesis of 2-(4(2)- (((4,6-dialkyl-5-oxo-2-thioxohexahydroimidazo[4,5-d]imidazol-1(2H)-yl)imino)methyl)phenoxy)acetates or acetamides (new substituted thioglycolurils) based on the reaction of 5,7-dialkyl-3-thioxoperhydroimidazo[4,5-e]-1,2,4-triazine-6-ones with functionally substituted aromatic aldehydes has been developed. Synthesized thioglycolurils with acetate function can undergo further simple transformation to the corresponding acetamides.
