A palladium-assisted coupling reaction of aryl triflate with arene was investigated, and a novel Pd reagent prepared from equimolar Pd(OAc)2, 1,3-Bis[diphenylphosphino]propane (DPPP), and Bu3P was developed. This method is useful for intramolecular biaryl coupling reactions, not only between aryl triflate and arene (triflate-amide), but also between aryl halide and arene (halo-amide).
研究了三氟甲磺酸芳基酯与芳烃的钯辅助偶联反应,并开发了由等摩尔Pd(OAc)2、1,3-双[二苯基膦基]丙烷(DPPP)和Bu3P制备的新型Pd试剂。该方法不仅可用于三氟甲磺酸芳基酯和芳烃(三氟甲酰胺)之间的分子内联芳基偶联反应,而且可用于卤代芳基和芳烃(卤代酰胺)之间的分子内联芳反应。
