| Abstract: | Irradiation of the title compound with d6 labeled Me groups I gave 2-methyl-d3-4-(9-phenanthryl)-1-butene-d3, which was elucidated on the bases of the spectral properties and chem. degradation Based on the discussions of MO and the bond order change between the designed pairs of basis orbitals on excitation, the most reasonable ring-opening mode of the title compound appeared to be the direct suprafacial 1,3-hydrogen migration. |
