Relative rates of [4 + 2] cycloadditions of cyclopentadienes 1a-1e with 4-phenyl-1,2,4-triazoline-3,5-dione (2) in 12 different solvents vary by factors of up to 19000, but the reactions show similar solvent effects. Rate constants k(2) correlate well with solvent parameters AN (positive correlation) and DN, SB (negative correlations), but not With E-T values.
