The reaction of an isolable anionic aluminabenzene with electrophiles, such as MeOTf and Me₃SiOTf, was investigated. The nucleophilic attack on the pentadienyl moiety of the aluminabenzene ring proceeded at the 4-position to form the aluminacyclohexadiene bearing a Me or Me₃Si group. Treatment of the resulting methyl- or silyl-substituted aluminacyclohexadiene with the bulky base MesLi gave the rearomatized anionic aluminabenzene bearing a Me or Me₃Si group. Thus, this sequential reaction would be considered as an electrophilic substitution of aluminabenzene. The substituent effect of Me and Me₃Si groups on the aluminabenzene ring was also estimated on the basis of experimental and theoretical studies.

通过与亲电试剂和碱的顺序反应，对阴离子铝苯进行亲电取代

研究了可分离的阴离子铝苯与亲电试剂（例如MeOTf和Me ₃ SiOTf）的反应。对铝苯环的戊二烯基部分的亲核攻击在4-位进行，以形成带有Me或Me ₃ Si基团的铝环己二烯。用笨重的碱MesLi处理所得的甲基或甲硅烷基取代的氧化铝环己二烯，得到带有Me或Me ₃ Si基团的重新芳构化的阴离子氧化铝苯。因此，该顺序反应将被认为是铝苯的亲电取代。在实验和理论研究的基础上，还评估了Me和Me ₃ Si基团对铝苯环的取代作用。
