In this study, we have employed dithiooxamide, a solid, odorless, and commercially available compound, as a sulfur surrogate for the preparation of dialkyl sulfides from available alkyl halides in high yields. This sulfur transfer agent was also used for a copper-catalyzed high-yielding preparation of diaryl sulfides from their available aryl halides and for the preparation of thia-Michael adducts
在这项研究中,我们使用二硫代草酰胺(一种固体、无味且可商购的化合物)作为硫代用品,以高产率从可用的卤代烷制备二烷基硫化物。这种硫转移剂还用于铜催化从可用的芳基卤化物制备二芳基硫化物的高产率,以及高产率制备硫杂-迈克尔加合物。所有反应均在无味条件下在湿 PEG200(PEG = 聚乙二醇)中进行,这是一种环保、安全且可回收的溶剂。这些协议很容易适用于大规模操作。
