[摘要]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 degrees C 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.
