Abstract
A facile, high yielding, method for the synthesis of a library of 2-aryl- and 2-heteroaryl-benzoxazoles and benzothiazoles from readily available Schiff bases is reported employing catalytic amounts of Pd(OAc) 2 in imidazolium ionic liquids (bmim)BF 4 and (bmim)PF 6 without ligands and/or additives. Simple product isolation and recycling/re-use of the IL are additional advantages of this method. © 2012 Elsevier Ltd. All rights reserved.
