Glyoxal bis(methylphenylhydrazone) 1 was prepared and examined as a ligand for the Suzuki-Miyaura cross-coupling reaction of aryl bromides and arylboronic acids. We found phosphine-free catalyst, such as Pd(OAc)2/hydrazone ligand 1 to be an efficient catalyst for a variety of substrates to produce the coupling products in good yields at room temperature.
二甲基苯肼化糖醛(Glyoxal bis(methylphenylhydrazone) 1)被制备并作为铃木-宫浦交叉偶联反应中芳基溴化物和芳基硼酸的配体进行研究。我们发现无膦催化剂,如Pd(OAc)2/肼配体1,是一种高效催化剂,能够在室温下对多种底物产生良产率的偶联产物。
