| Abstract: | Starting from 3, 4-dimethylfluorene the title compound, 5, 6-dimethyl-7, 12-dihydro-indeno1,2-a]fluorene (IV), is synthesized in four steps (overall yield 9%). The same hydrocarbon is also obtained in four steps starting from the phthalaconecarboxylic acid of Gabriel. This corroborates the structure of IV. |
