dichloromethane in the presence of added carbonyl compounds (3) resulted almost exclusively in monoozonolysis reactions to give the corresponding unsaturated cross-ozonides 8 and/or 10 as the major products. In contrast, ozonolysis of the nonconjugated olefins 1,5-cyclooctadiene (6a) and 1,5-dimethyl-1,5-cyclooctadiene (6b) under similar conditions afforded both unsaturated cross-ozonides (11 and 17, respectively)
在加入的羰基化合物 (3) 存在下,用一摩尔当量的臭氧在二氯甲烷中处理共轭 C5-至 C8-环二烯 (5a-5b) 几乎完全导致单臭氧分解反应,得到相应的不饱和交叉臭氧化合物 8 和/或 10 为主要产品。相比之下,非共轭烯烃 1,5-环辛二烯 (6a) 和 1,5-二甲基-1,5-环辛二烯 (6b) 在类似条件下的臭氧分解得到了源自单臭氧分解的不饱和交叉臭氧化物(分别为 11 和 17)和来自二臭氧分解的交叉臭氧化物(分别为 12 + 16 和 19)。
