- 中文摘要: Irradiation of bicyclo [ 2.2.2 ] oct-5-ene-2,3-diones(1a-c) proceeded quantitatively via 1,3-acyl shifts to yield the corresponding bicyclo [ 4.2.0 ] oct-2-ene-7,8- diones (2a-c) that underwent bisdecarbonylation to afford also quantitatively 1,3- cyclohexadienes upon further excitation. In contrast the thermolysis of (2c) produced(1c) and (4); the kinetic parameters were found to be.DELTA.H/sup .neq../=(90.4.plmin.0.8) kJ/mol and.DELTA.S/sup .neq./=(-12.1.plmin.0.1) J/K-mol.
