Transition-metal-free synthesis of thiazolidin-2-ones and 1,3-thiazinan-2-ones from arylamines, elemental sulfur and CO2

Transfering waste to treasure is highly important in green chemistry. However, it is difficult to realize it efficiently due to the low reactivity, especially the simultaneous utilization of two unreactive feedstocks in one reaction. Herein, we report the first utilization of both elemental sulfur and CO2 in a multi-component reaction to generate valuable thiazolidin-2-ones and 1,3-thiazinan-2-ones. Under transition-metal-free reaction conditions, a variety of easily available arylamines react with elemental sulfur and CO2 (1 atm) to give functional thiazolidin-2-ones and 1,3-thiazinan-2-ones in moderate to good yields via C-H bond functionalization. This strategy is highlighted by high step economy with generation of three bonds in one reaction and good functional groups tolerance.

Au@Cellulose/DFNS for synthesis of thiazolidin-2-ones from arylamines, elemental sulfur and CO2

Turning waste into valuable material is a remarkable phenomenon in sustainable chemistry. However, this reaction is not easy to perform due to the simultaneous employment of two low-reaction raw materials. In this study, we announce the employment of elemental sulfur and CO2 in a multi-element reaction to manufacture valuable thiazolidin-2-ones in the participation of Au@Cellulose/DFNS as a catalyst. In this method, three bonds in one reaction and functional groups with good tolerance were created. To generate the catalyst, DFNS was amended with cellulose through the click reaction and employed as a support for Au nanoparticles. Cellulose acted as both decreasing and consistency medium for Au NPs and removed the need for decreasing agent. The generated catalyst was distinguished by various techniques like XPS, TEM, TGA, SEM, ICP, and XRD analyses.
