The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Spectral study of the nitrogen derivatives of some aromatic aldehydes and ketones. III. N-Alkyl- and N-acyl-arylaldoximes.》. Authors are Grammaticakis, Panos.The article about the compound:1,2-Benzisoxazolecas:271-95-4,SMILESS:C12=CC=CC=C1ON=C2).Application In Synthesis of 1,2-Benzisoxazole. Through the article, more information about this compound (cas:271-95-4) is conveyed.
The ultraviolet absorption spectra of the N-alkyl and the N-acyl derivatives of the arylaldoximes are determined in the region 3750 to 2150 A. in alc. or cyclohexane solutions at concentrations 0.01, 0.001 and 0.0001 N. These include the N-benzyloxime of (o,p) methylbenzaldehydes; (o,m,p) methoxybenzaldehydes; N-(α-phenylpropyl)benzaldoxime, N-(α-p-tolylpropyl)benzaldoxime; N-(α-p-methoxyphenylpropyl)benzaldoxime; N-acetylanisaldoxime; N-acetylbenzaldoxime; N-carbamylbenzaldoxime; N-carbamylanisaldoxime; N-acetylsalicylaldoxime; N-carbamylsalicylaldoxime; benzisoxazole. The chromophore of the N-substituted arylaldoximes is more absorbing than those of the aryl aldoximes and of their O-substituted derivatives The absorption curves of the N-acyl derivatives of the arylaldoximes are displaced toward the ultraviolet relative to those of the corresponding N-alkyl derivatives and toward the visible relative to those of the oximes. The preparation and purification of all the substances studied are given.
Although many compounds look similar to this compound(271-95-4)Application In Synthesis of 1,2-Benzisoxazole, numerous studies have shown that this compound(SMILES:C12=CC=CC=C1ON=C2), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
