Virtanen, P. Olavi I.; Ruostesuo, Pirkko; Ruostesuo, Pirkko published an article about the compound: 1-(4-Chlorophenyl)pyrrolidin-2-one( cas:7661-33-8,SMILESS:O=C1N(C2=CC=C(Cl)C=C2)CCC1 ).Reference of 1-(4-Chlorophenyl)pyrrolidin-2-one. 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:7661-33-8) through the article.
The dipole moments of 1-phenyl-2-pyrrolidone and its 2′-methyl, 3′-methyl, 4′-methyl, 2′-chloro, 3′-chloro, 4′-chloro, 2′-methoxy, 3′-methoxy, and 4′-methoxy derivatives were measured in dioxane at 30° and the dipole moments of the 1st 4 compounds also in cyclohexane at 30°. The dipole moments were larger in dioxane than in cyclohexane. The dipole moments of all the compounds except 1-(3-methoxyphenyl)-2-pyrrolidone and 1-(4-methoxyphenyl)-2-pyrrolidone agree with the values calculated by applying Eyring’s treatment and assuming free rotation of the pyrrolidonyl group about the bond joining it to the aromatic ring.
In some applications, this compound(7661-33-8)Reference of 1-(4-Chlorophenyl)pyrrolidin-2-one is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
