An efficient method for the synthesis of 2-aminoindolizines by the 5-exo-dig cyclization of 2-alkyl-1-(1-cyanoalkyl)pyridinium salts has been developed. These substrates were prepared by N-alkylation of 2-alkylpyridines with readily available cyanohydrin triflates. The method allows the introduction of various substituents at the 1-, 3-, 6-, 7-, and 8-positions and leaves no undesired acceptor groups in the products. 2-Aminoindolizines have been synthesized from 2-alkylpyridines and readily available cyanohydrin triflates in two steps. This extension of the Tschitschibabin indolizine synthesis allows the introduction of various substituents at the 1-, 3-, 6-, 7-, and 8-positions and does not leave undesired electron-withdrawing groups in the products.

Retention of ionizable analytes under gradient elution depends on the pH of the mobile phase, the pKa of the analyte and their evolution along the programmed gradient. In previous work, a model depending on two fitting parameters was recommended because of its very favorable relationship between accuracy and required experimental work. It was developed using acetonitrile as the organic modifier and involves pKa modeling by means of equations that take into account the acidic functional group of the compound (carboxylic acid, protonated amine, etc.). In this work, the two-parameter predicting model is tested and validated using methanol as the organic modifier of the mobile phase and several compounds of higher pharmaceutical relevance and structural complexity as testing analytes. The results have been quite good overall, showing that the predicting model is applicable to a wide variety of acid-base compounds using mobile phases prepared with acetonitrile or methanol.

Modeling chemical reactions helps engineers virtually understand the chemistry, optimal size and design of the system, and how it interacts with other physics that may come into play. Formula: C7H9N

Rate constants (k) were measured for proton-transfer reactions from alkylbenzene ions RH+ to a series of reference bases B, i.e., RH+ + B -> BH+ + R*.For exothermic reactions (DeltaH BH+ + C6H5CH2* is fast (reaction efficiency = k/kcol >/= 0.5) when B = MeO-t-Bu or stronger bases, but k/kcol is significantly smaller when B is n-Pr2O or weaker bases.From the falloff curve of reaction efficiency vs.PA(B), we find PA(n-Pr2O) = PA(C6H5CH2*) + 0.8 kcal mol-1 = 200.0 kcal mol-1.Since PA(C6H5CH2*) is obtained from known thermochemical data, this relation defines the absolute PA of n-Pr2O.Through a ladder of known PA, we then obtain PA(i-C4H8) = 186.8 kcal mol-1; we also obtain the absolute PAs of other oxygen bases.Falloff curves of reaction efficiencies of 3-FC6H4CH3+, C6H5C2H5+, C6H5-n-C3H7+, and C6H5-i-C3H7+ with these reference bases give then the following PAs of R* and R-H bond dissociation energies (Do) (all in kcal mol-1) as R*, PA(R*), Do(R-H): 3-FC6H4CH2*, 197.2, 89.4; , 197.9, 86.2; , 199.1, 86.1; , 199.6, 86.1.In similar manner, rate constants for H+ transfer from C6H5NH2+ to reference pyridines and amines yield PA(C6H5NH*) = 221.5 and Do(C6H5NH-H) = 85.1 kcal mol-1 (1 kcal mol-1 = 4.18 kJ mol-1).

The presence of contaminants in the flue gas stream such as O2, CO2, SOX, and NOX can cause solvent degradation in solvent-based CO2 capture processes. In this study, the major degradation products reactions of the AMP-based CO2 capture process has been included in the Aspen Plus V8.4 simulation software using equilibrium reactions. Assessing the solvent degradation, solvent concentration and flowrate were varied. The results showed that the AMP losses reduced by decreasing solvent flowrate and concentration. Largest energy savings are observed when increasing concentration up to 34 wt. %.

A convenient and straightforward laboratory procedure is presented for a highly selective mono-alpha-methylation of pyridines without reactive functional groups. The methylating agent is probably carbon monoxide/dihydrogen generated in situ from a high-boiling alcohol on a metal surface. The reaction is catalyzed by a Raney nickel catalyst at ambient pressure, which renders the protocol practicable in standard organic laboratories. The intrinsically high reaction temperature and long reaction times restrict the application to pyridine derivatives with less reactive substituents. The outcome of the reaction can be rationalized by the assumption of a simple heterogeneous mechanism. Copyright Taylor & Francis Group, LLC.

A density functional theory (DFT) method was used to study the monomer and intermolecular charge-transfer complexes of 22 different alkylpyridines with diiodine. DFT calculations revealed that the sigma* orbital of iodine interacts with the nitrogen lone pair in pyridines. The open-circuit photovoltage (Voc) values of a bis(tetrabutylammonium)cis- bis(thiocyanato)bis(2,2?-bipyridine-4-carboxylic acid, 4?-carboxylate)ruthenium(II) (N719) dye-sensitized nanocrystalline TiO2 solar cell with an I-/I3- redox electrolyte in acetonitrile using alkylpyridines additive were compared to computational calculations on the interaction between pyridines and I 2 by a DFT method. The optimized geometries, frequency analyses, Mulliken population analyses, and interaction energies suggest that the V oc value of the solar cell is higher, the more alkylpyridine complexes with I2.

Synthetic and kinetic studies of the reactions between (Fe(1-5-eta-C6H7)(CO)3)+ (1) and X-substituted pyridines (X=H, 2-Me, 3-Me, 4-Me, 4-Ph, 2-Cl, 3-CN, 2,5-Me2, 2,6-Me2, 3,5-Me2, or 2,4,6-Me3) in CH3CN provide the first quantitative information on the importance of basicity and steric properties in controlling amine nucleophilicity towards co-ordinated ?-hydrocarbons.The products are pyridinium adducts of tricarbonyl(hexa-1,3-diene)iron.Similar pyridinium adduct formation occurs with cations (Fe(1-5-eta-2-MeOC6H6)(CO)3)+ (2) and (Fe(1-5-eta-C7H9)(CO)3)(BF4) (3).The general rate law rate = k1(Fe)(amine) is observed, except for the equilibrium reaction of (1) with 3-cyanopyridine which gives rate = k1 (Fe)(amine) + k-1 (Fe).The rate trend C6H7 > 2-MeOC6H6 > C7H9 found with several pyridines and the low DeltaH1<*> and large negative DeltaS1<*> values are consistent with direct addition to the dienyl rings.For attack of non-sterically crowded pyridines on (1), a Bronsted plot of log k1 versus pKa of the amine conjugate acid has a high slope alpha of 1.0, indicating a very marked dependence of rate on amine basicity.Successive blocking of the 2- and 6-positions of pyridine by methyl groups leads to marked non-additive steric retardation.
