Novel silica-coated ferrite nanoparticles supported with montmorillonite (K10) have been prepared successfully by using a simple impregnation method. Further, these nanoparticles were characterized by using different analytical methods like FT-IR, PXRD, EDS, and FE-SEM techniques. In addition, these nanoparticles have been explored for their catalytic activity for the O, N, and S-acylation reactions under solvent-free conditions which gave moderate to excellent yields in a much shorter reaction time. Moreover, these nanoparticles could easily be separated out from the reaction medium after the reaction completion by using an external magnetic field and have been re-used for 10 cycles without any significant loss of the catalytic activity.

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.

A series of S-acetylarenethiols were synthesized from aromatic amines by a rapid, convenient and efficient method. Arenediazonium tetrafluoroborates were afforded from aromatic amines, isoamyl nitrite and boron trifluoride etherate in non-aqueous diazotization system, then reacted with potassium thioacetate in dimethylsulfoxide to obtain desired products in moderate to good yields and short reaction times. The product S-acetyl-4-iodothiophenol was characterized by single crystal X-ray diffraction. The crystal belongs to monoclinic, space group P21/C with unit cell parameters: a = 0.594 20(12) nm, b = 0.542 00(11) nm, c = 2.9618(6) nm, α = 90.00°, β = 94.23(3)°, γ = 90.00°, Dx = 1.942 g/cm3, Z = 4, F(000) = 528, μ = 3.528 mm-1, R = 0.039 2, wR = 0.099 3, P = (Fo2 + 2Fc2)/3, S = 1.077, (Δρ)max = 0.692 x 1030 e/m3, (Δρ)min = -0.558 x 1030 e/m3. The X-ray crystallographic structure (CCDC-684683) clearly shows that the para atoms I and S lie in the benzene ring plane and no hydrogen bonds were observed.
