Intramolecular 1,5-transfer of a primary hydrogen atom is the dominant behaviour in dioxyl diradicals formed by flash vacuum pyrolysis of 5-substituted 3-methyl-1,2-dioxanes and is followed by decarbonylation when the substituent is the vinyl group.
伯氢原子的分子内1,5-转移是通过5-取代的3-甲基-1,2-
二恶烷的快速真空热解形成的二氧基双自由基的主要行为,当取代基为
乙烯基时,随后进行脱羰基化。
