The layers, in which cations and anions alternate, are parallel to each other. In the IR spectrum of compound 1, absorption bands at 1676 cm–1, 2949 cm–1, and 3021 cm–1 correspond to C=O and C–H stretching vibrations (aliphatic and aromatic). Compound 1 decomposes in two distinct steps. At the first step (172-200 °C), 4-acetyl-N,N,N-trimethylanilinium iodide decomposes with a removal of methyl iodide (i.e., inverse methylation reaction). At the second step (200-285 °C), 1-(4-(dimethylamino)phenyl)ethanon formed evaporates. Judging by the absence of the carbon residue, evaporation proceeds without decomposition.","PeriodicalId":668,"journal":{"name":"Journal of Structural Chemistry","volume":"66 9","pages":"1977 - 1984"},"PeriodicalIF":1.4,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145248267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
