Rostkowska, Hanna; Luchowska, Anna; Lapinski, Leszek; Nowak, Maciej J. published an article in 2021. The article was titled 《Effect of a Solid-Hydrogen Environment on UV-Induced Hydrogen-Atom Transfer in Matrix-Isolated Heterocyclic Thione Compounds》, and you may find the article in Journal of Physical Chemistry A.Product Details of 7748-36-9 The information in the text is summarized as follows:
To shed more light on the mechanisms of UV-induced hydrogen-atom-transfer processes in heterocyclic mols., phototautomeric thione → thiol reactions were investigated for thione compounds isolated in low-temperature Ar as well as in n-H2 (normal hydrogen) matrixes. These studies concerned thione compounds with a five-membered heterocyclic ring and thione compounds with a six-membered heterocyclic ring. The exptl. investigation of 2-thioimidazole and 3-thio-1,2,4-triazole (thione compounds with a five-membered heterocyclic ring) revealed that for the compounds isolated in solid n-H2 only trace amounts of thiol photoproducts were photogenerated; even though for the same compounds isolated in the solid Ar matrix, the thione → thiol photoconversion was nearly total. In contrast to that, for 3-thiopyridazine and 2-thioquinoline (thione compounds with a six-membered heterocyclic ring) isolated in solid n-H2, the UV-induced thione → thiol conversion occurred with the yield reaching 25-50% of the yield of the analogous process observed for the same species isolated in solid Ar. The obtained exptl. results allow us to conclude that the dissociation-association mechanism nearly exclusively governs the phototransformation in thione heterocycles with high barriers for tautomerization (such as thione compounds with a five-membered ring), whereas the strictly intramol. hydrogen-atom shift contributes to the mechanism of hydrogen-atom transfer in thione heterocycles with lower barriers (such as thione compounds with a six-membered ring). In the experimental materials used by the author, we found Oxetan-3-ol(cas: 7748-36-9Product Details of 7748-36-9)
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.Product Details of 7748-36-9
