“…Recently, significant attention of researchers has been focused on the obtaining of practically valuable compounds with the elimination of certain environmental restrictions and the use of new "green" methods, in particular, ultrasound-assisted reactions. 33,34,35 It is worth noting that in the case of S-methyl 4-(acetylamino)benzenesulfonothioate (A1) we have developed a production method that corresponds to the basic principles of "green chemistry". In particular, the alkylation reaction of the sodium salt of 4-acetylaminobenzenethiosulfonic acid with dimethyl sulfate was carried out in an environmentally safe solvent (water) under the influence of ultrasound.…”

A number of S-esters of 4-R-aminobenzene¬thiosulfonic acids were synthesized via alkylation of the sodium salt of 4-acetylaminobenzenethiosulfonic acid with various alkylating agents and acylation of the corresponding esters of 4-aminobenzenethiosulfonic acid with metha-cryloyl chloride. For obtaining S-methyl 4-(acetyla-mino)benzenesulfonothioate, it was developed a synthetic technique corresponding to the basic principles of "green chemistry". The degree of compound cytotox-icity was measured by determining A-549 cell growth using colorimetric method. The antibacterial activity of the thiosulfonates was determined by the agar diffusion test and the antiviral action by their cytopathic effect at TCID50 value.

“…However, the potential bacterial contamination of treated water and increasing its turbidity by bacterial metabolic products and byproducts is the main disadvantage. This risk is legitimate and the subsequent treatment (clarification) 8,9 and disinfection of water need to satisfy tap water standards.…”

The change of microorganisms number (rod-like spore-containing Bacillus cereus bacteria type) for the range of 102 ÷ 106 CFU in 1 cm3 from the duration of simultaneous action of ultrasound (US) cavitation and the nature of different gas (carbon dioxide, oxygen, argon) is presented. The graphical dependences of the effective rate constant values of microorganisms destruction (kd) on its initial number per unit volume of water at different modes of its treatment are shown. The destruction degrees of bacterial cells in the process of water purification are calculated. It was investigated that the value of kd does not depend on the initial number of cells in water, but depends on the nature of the bubbled gas through the reaction aqueous medium: kd(Ar/US) > kd(O2/US) > kd(CO2/US).

2-Benzylidenebenzofuran-3(2H)-ones commonly known as aurones, are an important class of oxygen heterocyclic compounds of flavonoid family. They exhibit some biological activities such as antioxidant, antifungal, anticancer, enzyme inhibitory, antiparasitic and antileishmanial activities. They are also responsible for imparting yellow color to the flowers and fruits. Owing to their varied importance, a simple and efficient method for the synthesis of 2-benzylidenebenzofuran-3(2H)-ones involving the reaction of 1-(2'-hydroxy-phenyl)-3-phenyl-propenones with copper acetate in ethanol under ultrasonic irradiation conditions has been described. The present method offers a faster reaction and a higher yield than conventional methods.
