An unsymmetrical disulfides synthesis by Cs2CO3‐catalyzed three‐component coupling reaction of thioacetate, sodium thiosulfate, and benzyl halide in water is described. The safe, stable, and non‐toxic Na2S2O3 was invoked as the sulfur‐source, successfully avoiding the odor generation in the process of S−S bond formation. A wide range of substrate suitability and appropriate functional group tolerance
描述了由Cs 2 CO 3催化的硫代乙酸盐,硫代硫酸钠和苄基卤化物在水中的三组分偶联反应合成的不对称二硫化物。安全,稳定且无毒的Na 2 S 2 O 3被用作硫源,成功避免了在S-S键形成过程中产生的气味。观察到广泛的底物适应性和适当的官能团耐受性用于转化。值得注意的是,此处报道的方法与各种生物分子兼容,包括葡萄糖,香豆素和喹啉酮。
