摘要：

[GRAPHICS] N,N-Bis-(2,6-diisopropylphenyl)dihydroimidazolium chloride with palladium(li) acetate (2 mol %) was used as catalyst, without added base, to efficiently cross couple aryl, vinyl, and alkyl boronates and boronic acids with aryldiazonium tetrafluoroborate substrates. The reactions were performed at 0 degreesC or rt, giving product in 2 to 4 h with 80 to 90% yields for isolated materials. Diazonium ions, formed in situ, also cross couple under these conditions.
