environmental awareness, the development of environmentally friendly reactions in aqueous media is the subject of an increasing number of studies. Hence, we report a novel three-component reaction of alkyl halides, thiourea and Bunte salts using non-toxic H2O as a benign reaction medium. After heating for 7 h, various unsymmetrical disulfides in high purity could be prepared in up to 92% yield. The substrates
由于当前的环境意识,在
水性介质中环境友好反应的发展是越来越多的研究主题。因此,我们报告了使用无毒的H 2 O作为良性反应介质的烷基卤化物,
硫脲和邦特盐的新型三组分反应。加热7小时后,可以以高达92%的收率制备各种高纯度的不对称二
硫化物。底物很容易获得,并且该方案不需要额外的氧化剂或还原剂。另外,不需要过渡
金属催化剂,使该方法对环境和经济都友好。
