Pyrrole | Aromatic, Heterocyclic, Nitrogen-Containing | Britannica
Pyrrole, any of a class of organic compounds of the heterocyclic series characterized by a ring structure composed of four carbon atoms and one nitrogen atom. The simplest member of the pyrrole family is pyrrole itself, a compound with molecular formula C4H5N.
15.5: Aromatic Heterocycles - Pyridine and Pyrrole
2024年9月30日 · Pyrrole (spelled with two r’s and one l) and imidazole are five-membered heterocycles, yet both have six π electrons and are aromatic.
Pyrrole | C4H5N | CID 8027 - PubChem
The epsilon-amino groups of lysyl residues react with 2,5-hexanedione forming pyrrole adducts, followed by pyrrole-mediated protein crosslinking. Both reaction steps have been proposed as mechanisms causing neurofilament accumulation and acceleration of transport.
Pyrrole - an overview | ScienceDirect Topics
Pyrrole is very much less basic than secondary amines but much more acidic. Pyrrole is, however, still a very weak acid (p K a = 17.5). The nitrogen-bound proton can be abstracted from pyrrole by the use of strong bases such as sodium amide …

15.5 Aromatic Heterocycles: Pyridine and Pyrrole - OpenStax
Pyrrole (spelled with two r’s and one l) and imidazole are five-membered heterocycles, yet both have six π electrons and are aromatic. In pyrrole, each of the four sp 2 -hybridized carbons contributes one π electron and the sp 2 -hybridized nitrogen atom contributes the two from its lone pair, which occupies a p orbital ( Figure 15.10 ).
