triphenylphosphine-mediated synthetic method for (Z)-diisopropyl-2-(cyano (aryl)methylene)hydrazine-1,1-dicarboxylates via one-pot three-component reactions using potassium hexacyanoferrate(II) as a cyanide source was described. This protocol has advantages of no use of strong toxic cyanating agents, high yield, and simple work-up procedure. GRAPHICAL ABSTRACT
