(at 150 °C) of trans-1 and cis-1 produced valerophenone (2) and butyl benzoate (3). Rationalization of the solid-state photoreactivity of the diperoxides by their crystal structures was attempted.Index abstractThe crystal structure of cis-valerophenone diperoxide (cis-1) shows whole molecule disorder. Its lower photoreactivity in the solid state is explained by the locally narrow and rigid reaction cavity
通过 X 射线晶体学分析阐明了 valerophenone diperoxides trans-1 和 cis-1 的晶体结构。两种化合物的 1,2,4,5-四
恶烷环均采用椅子构象。分子间CH···O氢键、π-π和CH/π相互作用存在于cis-1中,而trans-1中仅存在CH/π相互作用。在晶体的不对称单元中,半个分子为trans-1,而cis-1为一个分子,显示全分子无序。trans-1 和 cis-1 的固态光解(254 nm)或溶液态热解(150 °C)产生戊苯酮 (2) 和
苯甲酸丁酯 (3)。尝试通过其晶体结构合理化二过氧化物的固态光反应性。索引摘要顺式戊苯酮二过氧化物(cis-1)的晶体结构显示整个分子无序。
