Palladium pincer-complex-catalyzed selenylation of propargyl-, allyl-, benzyl-, and benzoyl halides could be achieved under mild reaction conditions employing trimethylstannylphenylselenide as selenylating agent. This reaction has a high functional group tolerance as carbmethoxy, tosylamino, nitro, aryl bromide, and unprotected hydroxy groups are tolerated. Mechanistic studies indicate that the catalytic
以三甲基锡烷基苯基硒化物为硒化剂,在温和的反应条件下,可以实现钯钳复合物催化的炔丙基,烯丙基,苄基和苯甲酰卤的硒化反应。该反应具有较高的官能团耐受性,因为可以耐受甲氧基,甲苯磺酰基氨基,硝基,芳基溴化物和未保护的羟基。机理研究表明,催化循环是通过形成硒配位的钯钳配合物而引发的,该配合物随后与亲电子底物反应。进行DFT计算以探索有机硒基团从钯向底物转移的机理。
