Abstract

Abstract: The cross-coupling reaction of bis-(pinacolato)diboron with chloroarenes to yield pinacol arylboronates was carried out in 1,4-dioxane at 80 degreesC in the presence of KOAc (1.5 equiv.) and Pd(dba)(2)/2.4PCy(3) (3-6 mol%). The catalyst was also effective to carry out analogous coupling with aryl bromides or triflates under milder conditions than those of the previous procedures catalyzed by PdCl(2)(dppf) in DMSO.
