Thermodynamic and infrared studies of tertiary amine oxide with bis(2,4-pentanedionato)oxovanadium(IV) was written by Popp, Carl J.;Nelson, John H.;Ragsdale, Ronald O.. And the article was included in Journal of the American Chemical Society in 1969.Synthetic Route of C7H9NO This article mentions the following:
The donor properties of a series of substituted pyridine N-oxide bases toward the reference acid bis(2,4-pentanedionato)oxovanadium(IV) [VO(acac)2] have been studied. Heats of reaction have been determined calorimetrically and, in the case of the 4-substituted pyridine N-oxide, correlate well with σPyNO. The change of the vanadium-vanadyl O stretching frequency (Δ v=o) and the vanadium-2,4-pentanedionate stretching frequency (Δ v-o) upon coordination were studied and were also found to correlate well with enthalpies of reaction. Substitution of alkyl groups in other than the 4 position of the pyridine N-oxide ring causes a decrease in the effective basicity toward the reference acid, VO(acac)2. The usefulness of VO-(acac)2 as a reference acid is discussed. The system is extended to the tertiary amine oxide p-bromo-N,N-dimethylaniline N-oxide and Me3NO. In the experiment, the researchers used many compounds, for example, 3,5-Dimethylpyridine 1-oxide (cas: 3718-65-8Synthetic Route of C7H9NO).
3,5-Dimethylpyridine 1-oxide (cas: 3718-65-8) belongs to pyridine derivatives. Pyridine has a conjugated system of six π electrons that are delocalized over the ring. The molecule is planar and, thus, follows the Hückel criteria for aromatic systems. Pyridine groups exist in countless molecules, and their applications include catalysis, drug design, molecular recognition, and natural product synthesis.Synthetic Route of C7H9NO
