Pd(II) acetate efficiently catalyzes a coupling of aryl, vinyl, and alkyl boronates and boronic acids with aryldiazonium tetrafluoroborates without added base in the presence of N,N-bis-(2,6-diisopropylphenyl)dihydroimidazolium chloride. The reactions were performed at low temperatures giving product in 2 to 4 h with very good yields. Diazonium ions can also be formed in situ.
