Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 91-76-9, Name is 2,4-Diamino-6-phenyl-1,3,5-triazine, molecular formula is , belongs to naphthyridine compound. In a document, author is Gou, Gao-Zhang, Category: naphthyridines.
Synthesis, Spectroscopic Properties and DFT Calculation of Novel Pyrrolo[1(‘),5(‘)-a]-1,8-naphthyridine Derivatives through a Facile One-pot Process
Novel pyrrolo[1(‘),5(‘)-a]-1,8-naphthyridine compounds (L1-L4) have been synthesized through a facile one-pot process by the reaction of the corresponding 1,8-naphthyridines with aliphatic anhydride. The structures were established by spectroscopic data. Further, X-ray crystal analysis of 7-diacetamino-2,4-dimethy-1,8-naphthyridine (L1) identifies its molecular structure and reveals pi- pi stacking. The synthetic mechanisms for L2, L3 were studied by density functional theory calculations. And a comprehensive study of spectroscopic properties involving experimental data and theoretical studies is presented. L1 exhibited electronic absorption spectrum with lambda (max) at similar to 320 nm. L2-L4 exhibited similar electronic absorption spectra with lambda (max) at similar to 390 nm that is tentatively assigned to pi ->pi* transition. The assignment was further supported by density functional theory (DFT) calculations.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 91-76-9, in my other articles.
