When developing chemical systems it’s of course important to gain a deep understanding of the chemical reaction process. Quality Control of 2,4-Dimethylpyridine

The reaction of pyridine and methylpyridines with alpha, beta-unsaturated carboxylic acids, such as: acrylic, methacrylic, crotonic, cinnamic, itaconic, fumaric and maleic acid, as well as the reactions of di- and trimethylpyridines with acrylic and maleic acids were studied. The reactions developed by such compounds may be, actually, considered as a competition between addition and neutralization, resulting betaine and/or salt. The factors influencing the development reaction are the chemical structure of the amine, acid and solvent, as well as the reaction duration. The order of reactivity for the same reactions was established by half-times. The 1H-NMR methodology was applied for elucidating both the chemically obtained structures and the half-times.

The ion mobility techniques, including the most commonly used drift-tube ion mobility spectrometry (IMS) and differential mobility spectrometry (DMS), are used successfully for the detection of a wide range of organic compounds in the gas phase. In order to improve detection quality, admixtures are added to gas streams flowing through the detector. Dopants mostly prevent the ionization of interfering chemicals however, better detection may be also achieved by shifting the peaks in the drift-time spectra, enabling ionization of analytes with low proton affinities and, thus, facilitating photoionization. Fundamental information about ion-molecule reactions including the role of dopants is presented. The term ‘gas modifiers’ refers to substances that influence the ion transport by changing the mobility of ions without changing the chemistry of the ionization. The mechanism of the gas modifier’s interaction with an analyte in ion separation in drift tube IMS and DMS is explained in this paper.

Either ZnCl2, Sc(OTf)3, or BF3OEt 2 can promote the palladium-catalyzed arylation of methylpyridines and related heterocycles (see example). The complexation of the Lewis acid to the nitrogen atom in the heterocycle facilitates the reductive elimination, leading to various arylated pyridines in high yields. BF3OEt 2 was also found to promote highly regioselective metalations in the case of 2,4-lutidine. Copyright
