Cheng, Kai published the artcileThe Pd(OAc)2-catalyzed homocoupling of arylboronic acids in water and ionic liquid, Related Products of pyridine-derivatives, the publication is Journal of Molecular Catalysis A: Chemical (2007), 273(1-2), 240-243, database is CAplus.
The homocoupling reaction of the arylboronic acids proceeded smoothly in a mixture of water and ionic liquids in the presence of Et bromoacetate ester using Pd(OAc)2 as catalyst in high yield at 60 °C for 3 h. The separation of desired products was easily performed by extraction with di-Et ether and Pd(OAc)2-[bmim][PF6] (1-butyl-3-methylimidazolium hexafluorophosphate) can be reused eight times accompanied with only a slight decrease in activity.
