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