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

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.
Acylation and alkoxycarbonylation of benzoxazoline-2-thione and benzothiazoline-2-thione

, p. 313 - 324 (2007/10/03)
Acylation of benzoxazoline-2-thione (1) and benzothiazoline-2-thione (2) with acetic anhydride (3) and acyl chlorides (4) gave N-acyl (5, 6) and/or S-acyl (7, 8) derivatives depending on the nature of acylating agents and bases used. Alkoxycarbonylation of 1 with aralkyl chlorocarbonates (9) gave N-alkoxycarbonyl derivatives (10) mainly, while that of 2 with aralkyl chloroccarbonates (9) gave S-alkoxycarbonyl derivatives (12) exclusively. Photolysis of N-acyl derivatives (5 or 6) in the presence of alcohols afforded 1 or 2, respectively, together with esters (16).
Organic reactions in ionic liquids: An efficient method for selective S-alkylation of 2-mercaptobenzothia(xa)zole with alkyl halides

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.
