Having gained chemical understanding at molecular level, chemistry graduates may choose to apply this knowledge in almost unlimited ways, as it can be used to analyze all matter and therefore our entire environment. 91-76-9, Name is 2,4-Diamino-6-phenyl-1,3,5-triazine, SMILES is NC1=NC(C2=CC=CC=C2)=NC(N)=N1, belongs to naphthyridine compound. In a document, author is Gou, Gao-Zhang, introduce the new discover, Quality Control of 2,4-Diamino-6-phenyl-1,3,5-triazine.
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.
Future efforts will undeniably focus on the diversification of the new catalytic transformations. In my other articles, you can also check out more blogs about 91-76-9. Quality Control of 2,4-Diamino-6-phenyl-1,3,5-triazine.
