In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Hydrogen bonding of pyrrole, indole and carbazole with substituted 1-phenyl-2-pyrrolidinones, published in 1979, which mentions a compound: 7661-33-8, mainly applied to LFER hydrogen bond phenylpyrrolidinone; equilibrium constant hydrogen bond; indole methylpyrrolidinone hydrogen bond; pyrrole methylpyrrolidinone hydrogen bond; carbazole methylpyrrolidinone hydrogen bond; IR hydrogen bond phenylpyrrolidinone, Name: 1-(4-Chlorophenyl)pyrrolidin-2-one.
The equilibrium constants (K) for the 1:1 H-bonded complexes between I (R = Me, Ph, substituted Ph) with pyrrole, indole, and carbazole were determined in CCl4 by IR. Hammett LFER were observed for each K and Δ υNH (the difference between pores and associated NH stretch). I (R = Me) is a stronger H acceptor than I (R = Ph, substituted Ph). The proton donor ability increases in the order; pyrrole < indole < carbazole. The ΔG°, ΔH°, ΔS° for the complexation are determined When you point to this article, it is believed that you are also very interested in this compound(7661-33-8)Name: 1-(4-Chlorophenyl)pyrrolidin-2-one and due to space limitations, I can only present the most important information.
