Synthesis, characterisation and bioactivity of polysubstituted 1-(4-(1H-pyrrol-1-yl)phenyl)-1H-pyrrole derivatives was written by Elassar, Abdel-Zaher A.. And the article was included in Journal of Chemical Research in 2012.COA of Formula: C18H10N2 This article mentions the following:
1,4-Phenylenediamine reacted readily with chloroacetone to give 1,4-bis[(2-oxopropyl)amino]benzene (I), which was used to prepare 1-[4-(1H-pyrrol-1-yl)phenyl]-1H-pyrroles in a 1-pot reaction with DMF-DMA or HC(OEt)3 and an active methylene nitrile, an active methylene ketone, or an arylidenemalononitrile. Reaction of I with arenediazonium salts afforded the hydrazones, which readily cyclized on reaction with malononitrile to give bis-pyrroles. The antibacterial activity of some of the products was determined In the experiment, the researchers used many compounds, for example, 2-(Anthracen-9-ylmethylene)malononitrile (cas: 55490-87-4COA of Formula: C18H10N2).
2-(Anthracen-9-ylmethylene)malononitrile (cas: 55490-87-4) belongs to nitriles. Nitriles are polar, as indicated by high dipole moments. As liquids, they have high relative permittivities, often in the 30s. Some nitriles are manufactured by heating carboxylic acids with ammonia in the presence of catalysts. This process is used to make nitriles from natural fats and oils, the products being used as softening agents in synthetic rubbers, plastics, and textiles and for making amines.COA of Formula: C18H10N2
