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.

An unsymmetrical disulfides synthesis by Cs2CO3-catalyzed three-component coupling reaction of thioacetate, sodium thiosulfate, and benzyl halide in water is described. The safe, stable, and non-toxic Na2S2O3 was invoked as the sulfur-source, successfully avoiding the odor generation in the process of S?S bond formation. A wide range of substrate suitability and appropriate functional group tolerance were observed for the transformation. Notably, the approach reported here was compatible with various biomolecules including glucose, coumarin, and quinolinone. (Figure presented.).

An efficient and convenient strategy for the preparation of diaryl sulfides via a Fe-promoted direct sulfuracylation of 2-naphthylamine using thioesters as bifunctional reagents is described. This synthetic strategy features high chemoselectivity, good substrate scope and functional group tolerance. (Figure presented.).

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.
S-Acetylation of Thiols Mediated by Triflic Acid: A Novel Route to Thioesters

, p. 489 - 493 (2018/04/27)
This paper demonstrates an efficient, mild, and chemoselective synthesis of various thioesters via a HOTf-catalyzed S-acetylation of aromatic and aliphatic thiols using isopropenyl acetate as a cheap and convenient acetylating agent. During our tests, we also investigated the differences between the activities of metal triflates and triflic acid as catalysts in the acetylation of thiols. Finally, the potential of our concept has been increased by the implementation of Nafion as a heterogeneous catalyst for S-acetylation of thiols.
Insertion of arynes into the carbon-oxygen double bond of amides and its application into the sequential reactions
Yoshioka, Eito,Miyabe, Hideto
experimental part, p. 179 - 189 (2012/02/15)
The reaction of arynes, generated from ortho-(trimethylsilyl)aryl triflates, with the CO bond of formamides gave salicylaldehyde derivatives via the formation of formal [2+2] adducts. The sequential transformation of arynes into ortho-disubstituted arenes, o-aminoalkylphenols or o-hydroxyalkylphenols, was achieved by one-pot procedure using dialkylzincs.
