Epoxides undergo efficient ring opening with potassium cyanide in acetonitrile in the presence of metal Schiff base complexes as catalysts. This method was carried out under neutral and mild conditions with both high yields and high regioselectivity within a short period of time. Thus, several beta-hydroxy nitriles, useful intermediates for the synthesis of biologically active molecules, were easily obtained at room temperature. (C) 2012 Elsevier Ltd. All rights reserved.
