Diarylselenides are a representative class of molecules in organoselenium compounds. We herein report a Rh-catalyzed direct diarylation of selenium with benzamide derivatives. The use of elemental selenium as the Se source is intriguing in terms of atom economy, cost, stability, and handling. A series of diarylselenides with amide moieties were readily accessible through directed C–H activation. The intermediacy of electrophilic Se(IV) species was indicated by control experiments.

Rh 催化元素硒与苯甲酰胺直接二芳基化合成二芳基硒化物

二芳基硒化物是有机硒化合物中一类具有代表性的分子。我们在此报道了 Rh 催化的硒与苯甲酰胺衍生物的直接二芳基化反应。使用元素硒作为硒源在原子经济性、成本、稳定性和处理方面都很有趣。通过定向 C-H 活化很容易获得一系列带有酰胺部分的二芳基硒化物。亲电子 Se(IV) 物种的中间性由对照实验表明。
