, p. 1 - 19 (2020)
Three naphthalimide aryl benzyl sulfide derivatives (NABSs) cleavable photoinitiators (PIs) containing benzyl-sulfur bonds were designed and prepared. The effect of the benzyl-sulfur moiety and substituents located on benzene ring of the benzyl group on p

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.).

The acid-catalyzed benzylic and allylic alkylation of protic nucleophiles is fundamentally important for the formation of carbon-carbon and carbon-heteroatom bonds, and it is a formidable challenge for benzylic and allylic amine derivatives to be used as the alkylating agents. Herein we report a highly efficient benzylic and allylic alkylation of protic carbon and sulfur nucleophiles with sulfonamides through double Lewis acid catalyzed cleavage of sp3 carbon-nitrogen bonds at room temperature. In the presence of a catalytic amount of inexpensive ZnCl2-TMSCl (TMSCl: chlorotrimethylsilane), 1,3-diketones, β-keto esters, β-keto amides, malononitrile, aromatic compounds, thiols, and thioacetic acid can couple with a broad range of tosylactivated benzylic and allylic amines to give diversely functionalized products in good to excellent yields and with high regioselectivity. Furthermore, the cross-coupling reaction of 1,3-dicarbonyl compounds with benzylic propargylic amine derivatives has been successfully applied to the one-step synthesis of polysubstituted furans and benzofurans.
A novel method for the synthesis of thioacetates using benzyltriethyl- ammonium tetrathiomolybdate and acetic anhydride
Nasir, Baig R. B.,Sai, Sudhir V.,Srinivasan, Chandrasekaran
experimental part, p. 2684 - 2688 (2009/04/16)
Herein we report a simple and efficient methodology for the synthesis of thioacetates using benzyltriethylammonium tetrathiomolybdate and acetic anhydride as the key reagents, starting from alkyl halides in a multistep, tandem reaction process. Its application in the synthesis of orthogonally protected cysteine and anomeric β-thioglycosides has also been demonstrated.
