Wischang, Diana; Hartung, Jens published an article about the compound: 4-Bromo-1H-pyrrole-2-carbonitrile( cas:1221435-18-2,SMILESS:BrC1=CNC(=C1)C#N ).Formula: C5H3BrN2. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:1221435-18-2) through the article.
Ester-, cyano-, and carboxamide-substituted 1H-pyrroles undergo electrophilic aromatic bromination, if treated with hydrogen peroxide and sodium bromide at pH 6.2 and 20 °C. Oxidation of bromide under such conditions is catalyzed by a vanadate(V)-dependent bromoperoxidase, in a substrate/enzyme ratio of 32-63 μmol %. To obtain maximum yields of bromopyrroles (up to 91%) by spending the least amount of substrate and catalyst, hydrogen peroxide and sodium bromide have to be added continuously to the enzyme and the 2-acceptor-substituted pyrrole (1.5 m mol) in a solution of morpholine-4-ethanesulfonic acid buffer. This technique was applied to prepare two marine natural products under biomimetic conditions, i.e., Me 4,5-dibromopyrrole-2-carboxylate (from Agelas oroides) and 4,5-dibromopyrrole-2-carboxamide (from Acanthella carteri).
From this literature《Parameters for bromination of pyrroles in bromoperoxidase-catalyzed oxidations》,we know some information about this compound(1221435-18-2)Formula: C5H3BrN2, but this is not all information, there are many literatures related to this compound(1221435-18-2).
