4-[(3,4-二甲氧基苯基)甲基]-1,2-二甲氧基苯 | bis(3,4-dimethoxyphenyl)methane | 1158-27-6 | C17H20O4 | 288.343 |
2,3,6,7-四甲氧基蒽醌 | 2,3,6,7-tetramethoxy-9,10-anthraquinone | 5629-55-0 | C18H16O6 | 328.321 |
The nuclear magnetic resonance data of some 9,10-dihydroanthracenes with substituents on the aromatic rings allow the assignment of a pseudoboat conformation for the central ring. The dihedral angle formed by the two planes in the molecule changes according to the substituents.
