Using cyclopalladated ferrocenylimine complexes (1-3 mol%) as catalysts, the Suzuki-Miyaura coupling of potassium N,N-dialkylaminomethyltrifluoroborates with aryl and heteroaryl halides were carried out in a 10:1 THF-H2O mixture at 80 ËC in the presence of Cs2CO3 (3.0 equiv) as base, giving the desired cross-coupling products in 14-87% yields. A variety of potassium alkyltrifluoroborates were also examined.
使用环钯化二茂铁亚胺配合物(1-3摩尔%)作为催化剂,在Cs2CO3(3.0当量)作为碱的存在下,在80 ℃的10:1 THF-H2O混合物中,进行钾N,N-二烷基氨基甲基三氟硼酸盐与芳基和杂芳基卤化物的铃木-宫浦偶联反应,得到了所需的交叉偶联产物,产率为14-87%。还研究了各种烷基三氟硼酸钾。
