Thermochemical studies of N-methylpyrazole and N-methylimidazole.
The 351.1 nm photoelectron spectra of the N-methyl-5-pyrazolide anion and the N-methyl-5-imidazolide anion are reported. The photoelectron spectra of both isomers display extended vibrational progressions in the X2A' ground states of the corresponding radicals that are well reproduced by Franck-Condon simulations, based on the results of B3LYP/6-311++G(d,p) calculations. The electron affinities...
متن کاملN-Methylimidazole Promotes the Reaction of Homophthalic Anhydride with Imines
The addition of N-methylimidazole (NMI) to the reaction of homophthalic anhydride with imines such as pyridine-3-carboxaldehyde-N-trifluoroethylimine (9) reduces the amount of elimination byproduct and improves the yield of the formal cycloadduct, tetrahydroisoquinolonic carboxylate 10. Carboxanilides of such compounds are of interest as potential antimalarial agents. A mechanism that rationali...
متن کاملDistribution of N-Methylimidazole in Ionic Liquids/Organic Solvents Systems
The partition coefficients, Kmim, of N-methylimidazole (mim) in two-component systems composed of ionic liquid (IL) and a series of organic solvents immiscible with ILs (butyl acetate, ethyl acetate, tert-butyl methyl ether, diethyl ether and cyclohexane) were determined by a shake-flask method. The influence of different factors such as temperature, solvent polarity, mim concentration, and wat...
متن کاملChameleonic Theories: A Short Review
In the chameleon mechanism, a field (typically scalar) has a mass that depends on the matter density of the environment: the larger is the matter density, the larger is the mass of the chameleon. We briefly review some aspects of chameleonic theories. In particular, in a typical class of these theories, we discuss the lagrangian, the role of conformal transformations, the equation of motion and...
متن کاملReactions of Imidoyl Isoselenocyanates with Aromatic 2-Amino- N-heterocycles and 1-Methylimidazole
The reaction of N-phenylimidoyl isoselenocyanates 1 with 2-amino-1,3-thiazoles 10 in acetone proceeded smoothly at room temperature to give 4H-1,3-thiazolo[3,2-a] [1,3,5]triazine-4-selones 13 in fair yields (Scheme 2). Under the same conditions, 1 and 2-amino-3-methylpyridine (11) underwent an addition reaction, followed by a spontaneous oxidation, to yield the 3H-4l4-[1,2,4]selenadiazolo[1’,5’...
