The developed protocol is ligand-, base-, and co-catalyst-free, sustainable, mild, inexpensive, and compatible with a wide range of aromatic/heterocyclic boronic acids and provides the corresponding products in excellent yields without purification. The catalyst was easily recovered from the reaction mixture and reused several times without loss of activity.</p>1 aMulla, Shafeek, Abdul Rash1 aChavan, Santosh, S.1 aPathan, Mohsinkhan, Y.1 aInamdar, Suleman, M.1 aShaikh, Taufeekaslam, M.
