✦ Synopsis


In a continuing study of cycloaddition reactions involving cyclopropane ring-containing systems (1) we have investigated the reactions of vinylcyclopropane and some substituted vinylcyclopropanes with 4-phenyl-1,2,4-triazoline-3,5-dione (PTAD) and chlorosulfonylisocyanate (CSI).

## Abstract 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__
