Fungicidal Activity of S-Esters of Thiocarboxylic Acids as Antimicrobial Additives to Petroleum Products
Abstract: A variety of aliphatic and aromatic S-esters of thiocarboxylic acids have been tested for antimicrobial activity. The relationship between the chemical structure of the compounds R1SC(O)R2 and their toxicity for microorganisms has been revealed, and the effect of various functional groups on the antimicrobial properties has been shown. The cooling lubricant IKhP-45E with S-aryl thioacetate additives has been tested. It has been shown that the additives used (0.25–0.5 wt %) inhibit the growth of all the studied microorganisms; however, their activity with respect to fungi is higher. The introduction of S-aryl thioacetates provides the resistance of these oils to microbiological deterioration to retain the physicochemical properties for a long period of time.

FUNCTIONALIZATION OF SATURATED HYDROCARBONS IN THE PRESENCE OF APROTIC ORGANIC SUPERACIDS. 2. SINGLE-STAGE SYNTHESIS OF THIOESTERS R1CO-SR FROM n-ALKANES OR CYCLOALKANES (RH), ELEMENTAL SULFUR, AND COMPLEXES R1COBr*2AlBr3
It has been found for the first time that n-alkanes and cycloalkanes (RH) can interact with elemental sulfur at ca. 20 deg C.These reactions go forward in the presence of aprotic organic superacids with the composition R1CO-SR in satisfactory yields.
