large majority of acyclic 1,4-dienes do not undergo photochemical di-π-methane (DPM) rearrangement under triplet-sensitized irradiation. The results of a detailed analysis of these processes demonstrate that a series of these compounds do indeed undergo highly efficient DPM rearrangement from their triplet excited states when suitable triplet sensitizers are used.
先前的研究得出的结论是,在三重态敏化辐射下,大多数无环1,4-二烯不经历光化学二-甲烷(DPM)重排。对这些过程进行详细分析的结果表明,当使用合适的三重态敏化剂时,一系列此类化合物确实确实会因其三重态激发态而发生高效的DPM重排。
