摘要:
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.
摘要:
Compounds of the formula: IN WHICH A is a halogeno-pyrimidyl or halogeno-s-triazinyl group are valuable dyestuff intermediates, notable for the speed of coupling of the derived diazonium salts. In the case of the triazine compounds, the heterocyclic nucleus can contain substituents other than halogen, notably methoxy, amino or sulphonated anilino and its common derivatives.
摘要:
Fiber-reactive monoazo and disazo compounds of the formula D-N.dbd.N--K which compounds are in free acid or salt form, and mixtures thereof, are useful for dyeing or printing hydroxy group- or nitrogen-containing organic substrates, for example leather and fiber material comprising natural or synthetic polyamides or natural or regenerated cellulose; the most preferred substrate is a textile material comprising cotton.
