The reactions of dimethylbutadiene with 1,2-naphthoquinones are shown to involve either addition to the 3,4-double bond [substituents 3-chloro-, 4-cyano-, 3-methoxycarbonyl, 3-nitro-, and 3-methoxy-(partially)] or to the 2-carbonyl group [substituents 4-chloro-, 4-bromo-, 3,4-dichloro-, 3-methoxy-(partially)]. The adduct from 3-chloro-1,2-naphthoquinone is shown to eliminate hydrogen chloride to yield
已显示二甲基丁二烯与1,2-萘醌的反应涉及3,4-双键的任何一种加成[取代基3-氯-,4-氰基-,3-甲氧羰基,3-硝基和3-甲氧基- (部分)]或2-羰基[取代基4-氯-,4-溴-,3,4-二氯-,3-甲氧基-(部分)]。显示了3-氯-1,2-萘醌的加合物消除了氯化氢,生成了菲-9,10-二醇,然后进行了酸催化的二甲基丁二烯加成,生成了羟基菲咯酮。
