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).
双反应(锍盐)7中的Na的溶液2 CO 3 H中2 O / EtOH中反应得到三个主要产物8 - 10。8的光谱数据与导致Mithcell和Sondheimer将其分配给环十[1,2,3- de:6,7,8- d'e' ]萘二萘的数据相同(3)。然而,我们的研究表明,正确的结构分配导致7,7a-二氢二苯并[ de,mn ]萘并苯的结构(8)。
