The photochemical and thermal behaviour of cyclic olefins like p-mentha-1,3,8-triene (2) and structural related p-mentha-1,3- and -1,4-dienes under the influence of oxygen have been investigated. Dehydration, ring opening, (4+2)-cycloaddition of singlet oxygen1 and dimerization were observed as concurring mechanisms. The photochemical and thermal dehydrogenation of α-terpinene (1), α-phellandrene (3)
已经研究了在氧的影响下,诸如对薄荷脑-1,3,8-三烯(2)和与结构相关的对薄荷脑-1,3-和-1,4-二烯等环状烯烃的光化学和热行为。脱水机制,开环,单线态氧1的(4 + 2)-环加成和二聚化被认为是同时发生的机制。α-萜品烯(1),α-芹菜烯(3),γ-萜品烯(4)和p-mentha-1,3,8-三烯(2)的光化学和热脱氢导致对苯甲基(5)和对-cy烯(6)。本文将讨论这种芳构化反应的机理。
