The structure of a hydrocarbon, m.p. 110–111·5°, obtained from two different cyclo-octatetraene dimers (V) and (VI) by hydrogenation followed by aluminium halide rearrangement has been determined by X-ray analysis to be an ethanocongressane, hexacyclo[10,3,1,02,10,03,7,06,15,09,14]hexadecane (III).
X射线分析确定,由两个不同的环
辛酸酯二烯(V)和(VI)加氢,然后进行卤化铝重排得到的烃的熔点为110–111·5°,其结构为
乙基环戊烷,六环[10,3,1,0 2,10,0 3,7,0 6,15,0 9,14 ]
十六烷(III)。
