Orthocyclophanes with Facing Benzene and Naphtahalene Rings
Dibenzo-, dinaphtho-, and benzonaphthobicycloundecan-11-ones 3,4 and 6a were converted into orthocyclophanes 8-10 and 12 by the reaction of the carbonyl group at the bridge with ethylene and propylene glycol, ethane-1,2-dithiol, and Grignard r
