Facile eco-friendly synthesis of 3,4,6,7-tetrahydro-3,3,6,6-tetramethyl-2H-xanthene 1,8(5H,9H)-dione, crystal structure and theoretical study was written by Tarannum, N.;Singh, M.. And the article was included in Crystallography Reports in 2014.Application of 4074-88-8 This article mentions the following:
New biol. active coumarin derivative, substituted xanthenedione was synthesized by an easy, facile, cost-effective and efficient method from dimedone and diethylene glycol diacrylate without use of expensive and hazardous catalyst. The synthesis is simple, short, high-yielding and also does not require expensive solvents. The compound was characterized by IR, NMR and x-ray crystallog. study. DFT (D. Functional Theory) calculations were performed at Becke’s 3-parameter functional and Lee-Yang-Parr functional (B3LYP) level of calculation and the 6-31G++ basis set was used for ground state geometry optimization. A comparison of the selected bond lengths and bond angles of the crystal structure and theor. optimized structure by DFT showed good agreement. The DFT study of electron surface potential (ESP), showed a large intramol. charge transfer efficiency of the mol. indicating optical activity of xanthenedione. Crystallog. data are given. In the experiment, the researchers used many compounds, for example, Diethyleneglycoldiacrylate (cas: 4074-88-8Application of 4074-88-8).
Diethyleneglycoldiacrylate (cas: 4074-88-8) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Application of 4074-88-8
