We present a study of the photofragmentation of three protonated azaindole mols. – 7-azaindole, 6-azaindole, and 5-azaindole – consisting of fused pyrrole-pyridine bicyclic aromatic systems, in which the pyridinic (protonated) nitrogen heteroatom is located at the 7, 6, and 5 positions, resp. Photofragmentation electronic spectra of the isolated aforementioned azaindolinium cations reveal that their photodynamics extends over timescales covering nine orders of magnitude and provide evidence about the resultant fragmentation pathways. Moreover, we show how the position of the heteroatom in the aromatic skeleton influences the excited state energetics, fragmentation pathways, and fragmentation timescales. Computed ab initio adiabatic transition energies are used to assist the assignation of the spectra, while geometry optimization in the excited electronic states as well as ab initio calculations along the potential surfaces demonstrate the role of ππ*/πσ* coupling and/or large geometry changes in the dynamics of these species. Evidence supporting the formation of Dewar valence isomers as intermediates involved in sub-picosecond relaxation processes is discussed. In the experiment, the researchers used many compounds, for example, Oxetan-3-ol(cas: 7748-36-9COA of Formula: C3H6O2)
Oxetan-3-ol(cas: 7748-36-9) is used as a reagent in the synthesis of 5-fluoro-4,6-dialkoxypyrimidine GPR119 agonists. It is also used as a reagent in the synthesis of cyclic sulfone hydroxyethylamines as potent and selective β-site APP-cleaving enzyme 1 (BACE1) inhibitors.COA of Formula: C3H6O2
