Study of denitrocyclization in synthesis of dibenzoxazepinones and dibenzothioazepinones was written by Sakharov, V. N.;Kalandadze, L. S.;Khristolyubova, T. A.;Smirnov, A. V.;Plakhtinskii, V. V.;Ivashchenko, A. V.. And the article was included in Izvestiya Vysshikh Uchebnykh Zavedenii, Khimiya i Khimicheskaya Tekhnologiya in 2008.Computed Properties of C9H8ClNO4 This article mentions the following:
The anal. of kinetic data of intermol. nucleophilic substitution of the 2′-nitro group in series of the diphenylsulfide- and diphenyloxide-2-carboxyamides with carboxyamide group participation has been carried out. The denitrocyclization reaction has been shown to proceed with Smiles rearrangement and spiro-蟽-complex formation limited the process of the dibenzothio- or dibenzoxazepinones. No data on the formation of dibenzothio- or dibenzoxazepinones are reported. In the experiment, the researchers used many compounds, for example, Ethyl 4-chloro-3-nitrobenzoate (cas: 16588-16-2Computed Properties of C9H8ClNO4).
Ethyl 4-chloro-3-nitrobenzoate (cas: 16588-16-2) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.Computed Properties of C9H8ClNO4
