Let’s learn more about this compound (cas:271-95-4).

Acid-catalyzed hydrolysis and intramol. nucleophilic anionic cyclization of acyloximes occur concurrently in H2O at pH 7-9; cationic micelles inhibit the hydrolysis reaction. Increasing the length of the acyl chain of 2-HOC6H4CH:NO2CR [R = Me, (CH2)4Me, (CH2)10Me] does not alter the micelle effect, possibly because the environment of the reacting species is not influenced by this variation in the structure.

COA of Formula: C7H5NO. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: 1,2-Benzisoxazole, is researched, Molecular C7H5NO, CAS is 271-95-4, about Aromaticity of anthranil and its isomers, 1,2-benzisoxazole and benzoxazole. Author is Domene, Carmen; Jenneskens, Leonardus W.; Fowler, Patrick W..

Direct computation of the π-c.d., i.e., the ‘ring current’, of anthranil (1) and its isomers 1,2-benzisoxazole (2) and benzoxazole (3) reveals different patterns of current flow: isomers sustain strong benzene-like currents in the six-membered and bifurcated flow in the five-membered ring, whereas, in keeping with its lower thermodn. stability, anthranil has only a perimeter circulation without sep. monocycle currents. Although the ring current criterion does not offer a sharp distinction between 2 and 3, their difference in thermodn. stability is identical to that between isoxazole and oxazole suggesting an aromaticity order 1 < 2 ≈ 3.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 1,2-Benzisoxazole, is researched, Molecular C7H5NO, CAS is 271-95-4, about Chemical evolution. XVII. Mechanisms of the photochemical rearrangements of ortho-substituted benzene derivatives and related heterocycles.Name: 1,2-Benzisoxazole.

The mechanisms of the photochem. rearrangements of isoxazoles, 2-cyanophenol, pyrazoles, and anthranilonitriles were investigated by using low-temperature techniques. Isonitrile (I) was detected by ir (2130 cm-1) and uv in the photoconversion of indoxazene to benzoxazole. I was further identified by independent synthesis and hydrolysis to the formanilide in acid. 2-Cyanophenol (II) is also formed on photolysis of indoxazene; however, no intermediate could be detected in this conversion. Quenching and sensitization studies suggest that the formation of benzoxazole proceeds from the singlet and II from the triplet excited states. The solvent dependence of the reaction suggests that benzoxazole is formed from an initial π,π* excitation and II is formed from an n,π* excitation. The photoconversion of II to benzoxazole may also proceed by I as shown by the uv spectrum of the reaction mixture after irradiation at – 77°. No intermediates were identified in the photochem. conversion of indazoles to benzimidazoles and anthranilonitriles using the above techniques. Emission measurements of the singlet and triplet energies of all the compounds used in this study are reported.
