Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 7661-33-8, is researched, SMILESS is O=C1N(C2=CC=C(Cl)C=C2)CCC1, Molecular C10H10ClNOJournal, Suomen Kemistilehti B called Dipole moments of substituted 1-phenyl-2-pyrrolidones, Author is Virtanen, P. Olavi I.; Ruostesuo, Pirkko; Ruostesuo, Pirkko, the main research direction is dipole moment phenylpyrrolidones; phenylpyrrolidones dipole moment; pyrrolidones phenyl dipole moment; methylphenylpyrrolidones dipole moment; chlorophenylpyrrolidones dipole moment; methoxyphenylpyrrolidones dipole moment.Name: 1-(4-Chlorophenyl)pyrrolidin-2-one.
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.
Compounds in my other articles are similar to this one(1-(4-Chlorophenyl)pyrrolidin-2-one)Name: 1-(4-Chlorophenyl)pyrrolidin-2-one, you can compare them to see their pros and cons in some ways,such as convenient, effective and so on.
