The reactions of aryl halides with 2,3,3-trimethyl-4-penten-2-ol in the presence of a palladium catalyst result in prenyl transfer from the alcohol to aryl halides via retro-allylation, yielding prenylarenes. Other multisubstituted allyl groups such as the 2,3-dimethyl-2-butenyl group are introduced to aromatic rings.
芳基卤化物与 2,3,3-三甲基-4-戊烯-2-醇在钯催化剂存在下的反应导致异戊二烯基通过逆烯丙基化从醇转移到芳基卤化物,产生异戊二烯。其他多取代的烯丙基如 2,3-二甲基-2-丁烯基被引入到芳环中。
