Electron spectroscopy offers great potential as a technique for chem. structure determination The N(1s) binding energies of tetraalkylammonium, and mono-, bi, and tricyclic aromatic quaternary N systems have been determined The order found in terms of decreasing binding energy was R4N+, pyridinium > isoquinolinium > quinolinium > acridinium, benzoquinolizinium. The effect of counterion on the binding energy was determined in the tetraalkyl series; ring substituent effects were investigated in the pyridinium series. The results are discussed in terms of MO calculations, electronegativity, crystal structure, and effects on basicity and electrophilic attack. The trend of the data indicates that certain structural information can be obtained from a single-atom correlation. However, the >5 eV spread observed for quaternary compounds indicates that single-atom correlations will be of limited value. The anion effects are sufficiently large that the counterion must be determined to correct for its effect. Some adjustment must also be made for substituent effects. The conclusion is that a multiple-atom correlation must be the approach used. In the experiment, the researchers used many compounds, for example, 1-Butyl-4-methylpyridin-1-ium bromide (cas: 65350-59-6Related Products of 65350-59-6).
1-Butyl-4-methylpyridin-1-ium bromide (cas: 65350-59-6) belongs to pyridine derivatives. Pyridine’s the lone pair does not contribute to the aromatic system but importantly influences the chemical properties of pyridine, as it easily supports bond formation via an electrophilic attack. Pyridine, its benzo and pyridine-based compounds play diverse roles in organic chemistry. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. Related Products of 65350-59-6
