✦ Synopsis

The rate constants of the electrocyclic ring closure of of theoretical predictions, neither solvent nor salt effects. For the ring opening of 3, small solvent and salt effects were (1Z,3Z,5E)-1,2,6-triphenylhexa-1,3,5-triene (1) and of the ring opening of dimethyl 3,4-dimethyl-1,2-diphenylcyclo-found, suggesting the possibility of observing small acceleration due to specific solute-solvent or salt inter-butene-cis-3,4-dicarboxylate (3) were determined in 15 and 16 solvents, respectively. The ring closure of 1 shows, in spite actions.
