for the highly efficient Suzuki–Miyaura reaction of aryl and heteroarylchlorides. The couplings of various aryl chlorides with arylboronic acids in aqueous ethanol were efficiently achieved in the presence of 1.0 mol% of the catalyst. Furthermore, the scope of this catalyst was extended to the coupling of heteroarylchlorides. Regardless of the substituents, all of the coupling reactions were very clean

be a highlyactive and long-lived catalyst for aqueous Suzuki, Stille and Sonogashira couplingreactions of heteroarylchlorides. A wide range of heteroarylchlorides could be efficiently coupled with different nucleophilic partners in the presence of only 0.5 mol% catalyst and undermildconditions. This is one of the most powerful heterogeneous catalysts for the couplings of diverse heteroaryl chlorides
