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

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.

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.

Rationale When dopants are introduced into the buffer gas of an ion mobility spectrometer, spectra are simplified due to charge competition. Methods We used electrospray ionization to inject tetrahydrofuran-2-carbonitrile (F, 2-furonitrile or 2-furancarbonitrile) as a buffer gas dopant into an ion mobility spectrometer coupled to a quadrupole mass spectrometer. Density functional theory was used for theoretical calculations of dopant-ion interaction energies and proton affinities, using the hybrid functional X3LYP/6-311++(d,p) with the Gaussian 09 program that accounts for the basis set superposition error; analytes structures and theoretical calculations with Gaussian were used to explain the behavior of the analytes upon interaction with F. Results When F was used as a dopant at concentrations below 1.5 mmol m-3 in the buffer gas, ions were not observed for alpha-amino acids due to charge competition with the dopant; this deprotonation capability arises from the production of a dimer with a high formation energy that stabilized the positive charge and created steric hindrance that deterred the equilibrium with analyte ions. F could not completely strip other compounds of their charge because they either showed steric hindrance at the charge site that deterred the approach of the dopant (2,4-lutidine, and DTBP), formed intramolecular bonds that stabilized the positive charge (atenolol), had high proton affinity (2,4-lutidine, DTBP, valinol and atenolol), or were inherently ionic (tetraalkylammonium ions). Conclusions This selective deprotonation suggests the use of F to simplify spectra of complex mixtures in ion mobility and mass spectrometry in metabolomics, proteomics and other studies that generate complex spectra with thousands of peaks.
