Highly efficient Suzuki-Miyaura coupling of aryl halides with arylboronic acid was realized in 50% aqueous ethanol at room temperature employing Pd(OAc)(2) immobilized in diethylaminopropylated (NDEAP) alumina pores with the aid of [bmim]PF(6), which enabled recycle use up to five times in 95% average yield and turnover number of two million.
