Method for synthesizing asymmetric selenium sulfide through cross coupling of diselenide and sulfoxide

The invention discloses a method for synthesizing asymmetric selenium sulfides through cross coupling of diselenide and sulfoxide, which is characterized in that a series of different asymmetric selenium sulfides are prepared under simple and convenient synthesis conditions through cross coupling reaction of diselenide compounds and sulfoxide compounds. The strategy has the characteristics of no metal participation, simple conditions, wide substrate range, good functional group tolerance and high yield, and provides an efficient and green way for the preparation of the asymmetric selenium sulfide in a highly concise manner. 本发明公开了一种二硒醚和亚砜的交叉偶联合成不对称硒硫化物的方法，该方法通过二硒醚类化合物和亚砜类化合物的交叉偶联反应，在简便的合成条件下，制备获得一系列不同的不对称的硒硫化物。该策略的特点是无金属参与、条件简单、底物范围广、官能基团耐受性好，产率高，以高度简洁的方式为不对称硒硫化物的制备提供了一个高效绿色的途径。
