Subsequent reaction with electrophiles such as allyl bromide and propargyl bromide occurs selectively at position 1, resulting in the formation of the novel 1-allylacenaphthene and 1-propargylacenaphthene. In addition to what was observed in the case of methyl iodide, the hitherto unknown 1,1-dialkylated acenaphthene derivatives are formed as minor products; probably the lower reactivity of the unsaturated
通过用一当量甲醇质子化,苊的二价阴离子可以转化为5-氢阴离子。随后与亲电子试剂如烯丙基溴和炔丙基溴的反应选择性地发生在 1 位,导致形成新的 1-烯丙基萘和 1-炔丙基。除了在甲基碘的情况下观察到的之外,还形成了迄今为止未知的 1,1-二烷基化苊衍生物作为次要产物;不饱和溴化物的较低反应性可能是造成这种副反应的原因。从与 3,3-二甲基烯丙基溴和(溴甲基)环丙烷反应的产物中,发现机理是 SN2。氢阴离子与苄基溴的反应发生在位置 1 以及位置 2a。
