The reactivity of alfa-beta-unsaturated p-Tosylhydrazones toward ion cyanide as nucleophile. In a aqueous-dichloromethane two-phases reaction, using benzyltriethyammonium chloride as a phase-transfer catalyst, we obtained hydrocyanation of tosylhydrazones of cycloexanone and other unconjugated substrates, while the C=N of conjugated one, resists nucleophilic attack of cyanide ion.
