Abstract

Procedure for the preparation of new derivatives of dibenzocyclopropapentalene of the general formula **(See formula)** in which R1 and R2 each represent hydrogen, the methyl group or the ethyl group and A stands for an alkylene radical with up to 3 carbon atoms, as well as its salts with inorganic or organic acids, characterized in that an ester suitable for the reaction of a compound of the general formula II, **(See formula)** in which A has the significance indicated under formula I, is reacted with a compound of general formula III **(See formula)** in which R1 and R2 have the significance indicated under formula I, or with an alkali metal derivative of one of such compounds and the reaction product is optionally transformed with an inorganic or organic acid into an addition salt.
