A Pd/norbornene/Cu cooperative catalysis for the efficientsynthesis 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。
AbstractA metal‐free, tetraethylammonium bromide‐catalyzed oxidative coupling of aldehydes or alcohols with thiophenols or disulfides has been developed. This protocol affords an efficient and inexpensive approach to the synthesis of a wide range of thioesters in high yields.magnified image
