Synthesis of Dithiapropellanes with Annelated Benzene Rings–Precursors for Molecules with the Benzene‐Dewar Benzene Structure

Benzoannelated analogues of l,4-polymethylene-(Dewar)benzene derivatives, e.g. (3) and (4), are obtainable from the dithiapropellanes (1) and (2) (X, Y = S). (2) and (4) are chiral.
