state in one case supports the conclusion. The vapour-phase results further suggest the existence of both diradical and concerted pathways for the [1,3]-acyl shift from the excited singlet state, and the possibility of a similar pattern from the higher triplet state.
研究了在溶液和汽相中直接照射三种βγ-不饱和酮时观察到的不可抑制的ODPM反应。结果表明较高的三重态可能是该反应的起源。在一种情况下,这种激发态的热产生支持了这一结论。蒸气相的结果进一步表明,从激发单重态转变为[1,3]-酰基的双自由基和协同途径都存在,而从更高的三重态转变为类似形式的可能性也存在。
