Reaction of 8,16-dimethyl[2.2]metacyclophan-1-enes with protonic acids such as 57% hydroiodic acid and trifluoroacetic acid afforded the corresponding 10b,10c-dihydro-10b,10c-dimethylpyrenes. Similar reaction with 47% hydrobromic acid and 36% hydrochloric acid gave surprisingly halogenated 10b,10c-dihydro-10b,10c-dimethylpyrenes.
8,16-二甲基[2.2]偏环-1-烯与质子酸(如 57% 的氢碘酸和三氟乙酸)反应,可得到相应的 10b,10c-二氢-10b,10c-二甲基吡喃。与 47% 的氢溴酸和 36% 的盐酸进行类似的反应,可以得到令人惊讶的卤代 10b,10c-二氢-10b,10c-二甲基吡喃。
