It has been shown that the
reaction of aluminium chloride with tetralin yields
6,6'-(butane-1,4-diy1)-bis(1,2,3,4-tetrahydronaphthalene) as well as a number
of other products. It is suggested that this compound is formed by protonation
of tetralin, fragmentation of the alicyclic ring and
then electrophilic attack of a further tetralin
molecule. The positions of substitution in the product suggests that ion pairs
are involved in the reaction. It is clear that intermediates have sufficient lifetime to undergo intermolecular
substitution reactions in addition to intramolecular substitution or proton loss.

6,6'-(丁烷-1,4-二1)-双(1,2,3,4-四氢萘)以及其他一些产物。
其他一些产物。据推测,这种化合物是通过质子化
四氢萘的质子化、脂环的破碎和
然后与另一个四氢萘分子发生亲电作用。
分子的亲电作用。产物中的取代位置表明,离子对
参与了反应。很明显,中间产物具有足够的寿命,除了发生分子内取代反应外,还能发生分子间取代反应。
除了分子内取代或质子损失外,中间体显然还有足够的寿命来进行分子间取代反应。
