Abstract

The straightforward organocatalytic insertion of carbon disulfide (CS₂) into epoxides using either choline chloride (ChCl) or tetrabutylammonium chloride (TBACl) is reported, for the first time, under solvent-free (neat) conditions. Fine-tuning of our system allowed us to obtain either dithiocarbonates (DTCs) or trithiocarbonates (TTCs) with high efficiency. Additionally, a mechanistic proposal is presented, supported by experimental evidence, DFT calculations and wavefunction analyses.

本研究首次报道了在无溶剂（纯净）条件下使用氯化胆碱（ChCl）或四丁基氯化铵（TBACl）将二硫化碳（CS2）直接有机催化插入环氧化物的过程。通过对系统进行微调，我们可以高效地获得二硫代碳酸酯（DTC）或三硫代碳酸酯（TTC）。此外，在实验证据、DFT 计算和波函数分析的支持下，我们还提出了一个机理建议。
