    • Cyclization of a dialkali metal salt of 1,1,2,3-4,4-hexacyano-2butenediide with acid yeilds 1-amino-2,3-4,5,5pentacyanocyclopentadiene which is converted to 1-amino-2,34,5,5-tetracyanocyclopentadiene which is converted to 1-amino2,3,4,5-tetracyanocyclopentadiene with strong mineral acid. Reaction of the pentacyanocyclopentadiene with nitrous acid gives 1-diaza-2,3,4,5-tetracyanocyclopentadiene which can be reacted with trialkyl or triaryl phosphorus to give 1-tri(aryl or alkyl)phosphazino-2,3,4,5-tetracyanocyclopentadiene. The diazotetracyanocyclopentadiene compound can be reacted with alkali metal compounds preferably under reducing condition to yield salts wherein the diazo group is replaced with hydrogen, amino, cyano, hydroxy, carboxy, alkoxycarbonyl, alkyl, aryl, phydroxyphenyl, nitro and mercapto groups. The cyanocyclopentadiene compounds are useful as rodenticides and as rocket propellants.
