The reaction of the bis(sulfonium salt) 7 in a solution of Na 2 CO 3 in H 2 O/EtOH yielded three main products 8 – 10 . The spectroscopic data of 8 were identical to those which led Mithcell and Sondheimer to assign them to cyclodeca[1,2,3‐ de : 6,7,8‐ d′e′ ]dinaphthalene ( 3 ). Our investigations show, however, that the correct structural assignment leads to the structure of 7,7a‐dihydrodibenzo[ de , mn ]naphthacene ( 8 ).
