Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels.In a patent， name: N1-(2-(Dimethylamino)ethyl)-N1,N2,N2-trimethylethane-1,2-diamine, Which mentioned a new discovery about 3030-47-5
Complexed tetrahydrofuran in magnesium anthracene * 3THF (1) is displaced by mono-, bi-, and tridentate ligands L (L= dioxane, 1,2-dimethoxyethane, ethylbis(2-methoxyethyl)amine, pentamethyldiethylenetriamine, 1,4,7-trimethyl-1,4,7-triazacyclononane) affording the magnesium anthracene complexes C14H10Mg * n L (2a-e); upon reaction of 1 with tetramethylethylenediamine (TMEDA) magnesium anthracene * THF * TMEDA is formed.The new magnesium complexes 2a-e are protolysed to Mg2+, 9,10-dihydroanthracene, and L.In solvents of low Lewis basicity (ether, hydrocarbons) 1 decomposes, probably via magnesium anthracene * 2 THF, to active magnesium, anthracene, and THF.A similar behaviour in toluene is displayed also by magnesium butadiene * 2 THF.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 3030-47-5, help many people in the next few years.name: N1-(2-(Dimethylamino)ethyl)-N1,N2,N2-trimethylethane-1,2-diamine
