Ionic liquids based on 1-butyl-3-methylimidazolium hexafluorophosphate (BmimPF6) and 1-butyl-3-methylimidazolium tetrafluoroborate (BmimBF4) are used as reusable reaction medium in the selective S-alkylation of 2-mercaptobenzothia(xa)zole with alkyl halides in the presence of potassium carbonate. This procedure is convenient, efficient, and generally gives rise to the S-alkylated product exclusively.

Microwave-assisted, solvent-free alkylation and acylation of 2-mercaptobenzothiazole has been attempted using silica gel, alumina, and a new solid support, fly ash. Fly ash, a waste generated at thermal power stations, could be used as solid support just as efficiently as commercial supports. The additional features of methodology include a much faster reaction, easy workup, higher yields, higher purity of the products, and an ecofriendly approach. Copyright Taylor & Francis Group, LLC.
Synthesis and application of new S-benzoheterocycle thiobenzoates photoinitiators
Zhao, Ziren,Wang, Chen,Liu, Feng,Zhang, Bianxiang
, p. 3717 - 3726 (2020/05/11)
A series of free radical photoinitiators with thioester bonds were synthesized by the nucleophilic substitution reaction of acyl chloride and thiol or thiophenol. These compounds could be efficiently obtained under mild reaction conditions and were fully
Selective approach to thioesters and thioethers via sp3 C-H activation of methylarenes
Feng,Lu,Cai
, p. 54409 - 54415 (2015/01/16)
Novel C-S cross-dehydrogenative coupling (CDC) approaches for the selective synthesis of thioesters and thioethers have been developed via sp3 C-H activation of methylarenes and subsequent functionalization. The reaction of methylarenes with thiols resulted in thioesters in the presence of a FeBr2/TBHP system, while treatment of methylarenes with thiols in the Pd(OAc)2/O2/TBHP system led to the formation of thioethers. Both the green protocols demonstrate good functional group tolerance and satisfactory yields. This journal is
Syntheses of thiol and selenol esters by oxidative coupling reaction of aldehydes with RYYR (Y = S, Se) under metal-free conditions

supporting information, p. 6072 - 6075 (2014/08/05)
Thiol and selenol esters were synthesized by a direct oxidative coupling reaction of aldehydes with disulfides or diselenides in ethyl acetate under metal-free conditions. Among the oxidants examined, tert-butyl peroxide (TBP) was shown to give the best results. For the substrates with both electron-donating and electron-withdrawing substituents, the reaction proceeded smoothly and gave moderate to good yields. Compared with the previous method, the present route is very simple, atom-economical and environmentally friendly. This journal is the Partner Organisations 2014.
Ultrasound promoted synthesis of thioesters from 2-mercaptobenzoxa(thia)zoles
Duarte, Anaí,Cunico, Wilson,Pereira, Claudio M.P.,Flores, Alex F.C.,Freitag, Rogério A.,Siqueira, Geonir M.
experimental part, p. 281 - 283 (2010/12/25)
An ultrasound-enhanced method has been developed for the synthesis of a variety of thioesters from benzoyl chlorides and 2-mercaptobenzoxa(thia)zoles. Applying this methodology, 14 compounds were synthesized in excellent yields.
