A Pd/norbornene/Cu cooperative catalysis for the efficient synthesis of 2-(arylthio)aryl ketones from aryl halides and thioesters has been developed. The first example of cooperative catalysis by palladium, norbornene, and copper, wherein the C(O)-S bond of thioesters is cleaved by a Pd(II) palladacycle with the assistance of CuI, has been observed.
已经开发了一种用于从芳基卤化物和硫酯有效合成 2-(芳硫基)芳基酮的 Pd/降冰片烯/Cu 协同催化。已经观察到钯、降冰片烯和铜协同催化的第一个例子,其中硫酯的 C(O)-S 键在 CuI 的帮助下被 Pd(II) 钯环裂解。
