Starting from 2‐methyl‐ and from 2,3‐dimethyl‐1,4‐diphenyl‐butadiene‐1, 3 respectively, the 5‐methyl‐ and the 5,6‐dimethyl‐11, 12‐dihydro‐indeno[2.1‐ a ]fluorene are synthesized in 4 steps. The 5, 6‐diphenyl‐11, 12‐dihydro‐indeno[2.1‐ a ]fluorene is obtained by reduction of the already known 11, 12‐dioxoderivative. Accesorily a new preparation of the unsubstituted hydrocarbon is described.
