Mercury-activated calcium readily forms an adduct with acenaphthylene in tetrahydrofuran at –35°. Rapid carboxylation gives acenaphthene-trans-1,2-dicarboxylic acid as the only acidic product, whereas slow carboxylation produces two further isomeric diacenaphthyl dicarboxylic acids. One of these isomers has been obtained in dimorphic forms, the dimethyl esters of which are thermally interconvertible
汞活化的钙很容易在–35°C与四氢呋喃中的形成加合物。快速羧化产生烯-反-1,2-二羧酸作为唯一的酸性产物,而缓慢羧化产生另外两种异构体二ac基二羧酸。这些异构体中的一种已经以双晶形式获得,其二甲基酯是可热互变的。钠与苊的加成物也已经准备和羧基化,得到acenaphthene-反式- 1,2-二羧酸。
