The Knoevenagel reaction between 2-hydroxybenzaldehydes and active methylene compounds (malononitrile and ethyl cyanoacetate) produces iminocoumarins and/or coumarins. In order to study the reactivity of the prepared iminocoumarins, chlorination and reaction with N-nucleophiles were studied. (c) 2005 Elsevier Ltd. All rights reserved.
