|標題:||Direct Observation of the Molecular Structural Changes during the Claisen Rearrangement Including the Transition State|
Department of Electrophysics
|摘要:||The detailed processes in the Claisen rearrangement were observed. The process was vibrationally excited in the electronic ground state by a stimulated Raman process using a 5-fs pulse. The Claisen rearrangement was found to follow a three-step pathway. At first, the C(4)-O bond is weakened to generate a bis-allyl-like intermediate. Next, the formation of a weak C(1)-C(6) bond results in the generation of an aromatic-like intermediate. Finally, C(4)-O breaking and C(1)-C(6) formation occur simultaneously to generate the product.|
