Herein, we disclose the synthesis of diaryl selenides through an unexpected C–Se coupling between aryl benzyl selenoxides and phenols. The synthetic significance of the method is that it provides a mild, rapid, and metal-free access to organoselenides in high yields with excellent functional group tolerance. This coupling of aryl benzyl selenoxides reveals a completely new reaction possibility compared
在这里,我们公开了通过芳基苄基亚硒酸酯和苯酚之间意外的C-Se偶联合成二芳基硒化物的方法。该方法的综合意义在于,它可提供温和,快速且无金属的有机硒化物,且具有出色的官能团耐受性。与芳基亚砜相比,芳基苄基亚硒酸酯的这种偶联揭示了全新的反应可能性。我们还通过实验研究探索了这种意外转变的反应机理,并揭示了一种特殊的Se(IV)-Se(III)-Se(II)反应途径。
