摘要

The photochemistry of diazocyclohexadienone (1), o-phenylene thioxocarbonate (2), and 2- chlorophenol (3) in solution was studied using time-resolved UV–vis and IR transient absorption spectroscopies. In these three cases, the same product cyclopentadienyl ketene (5) is formed, and two different mechanistic pathways leading to this product are discussed:(a) rearrangement in the excited state (RIES) and (b) a stepwise route involving ...
