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.
