We report a diaryldiselenide catalyst for cross-dehydrogenative nucleophilic functionalization of hydrophosphoryl compounds. The proposed organocatalytic cycle closely resembles the mechanism of the Atherton-Todd reaction, with the catalyst serving as a recyclable analogue of the halogenating agent employed in the named reaction. Phosphorus and selenium NMR studies reveal the existence of a P-Se bond intermediate, and structural analyses indicate a stereospecific reaction.
我们报告了一种二芳基二硒化物催化剂,用于氢膦酰基化合物的交叉脱氢亲核官能化。所提出的有机催化循环与 Atherton-Todd 反应的机制非常相似,催化剂是所命名反应中所用卤化剂的可回收类似物。磷和硒 NMR 研究揭示了 P-Se 键中间体的存在,结构分析表明反应具有立体特异性。
