Odourless Strategy for Deep Eutectic Solvent-Mediated Ring Opening of Epoxides with In Situ Generated S-Alkylisothiouronium Salts
摘要:
A general, straightforward and odourless ring-opening reaction allows the preparation of beta-hydroxy sulfides from in situ generated S-alkylisothiouronium salts in urea-choline chloride-based deep eutectic solvent (DES). In addition, reaction of epoxides with thiourea in DES yields the corresponding thiiranes.
