The Houben-Hoesch synthesis of from activated aromatic substrates and nitriles in the presence of HC1 and ZnC1, has been reviewed by Ruske." An abnormal HoubenHoesch reaction of resorcinol with f&ketonitriles,5 proceeds first via the keto group and then the nitrile to afford coumarins. This reaction falls within the scope of the von Pechmann reaction.6 This communication reports a drastic deviation
