3-Chlorocyclopent-1-ene → 2-(cyclopent-2-en-1-yloxy)-2,3-dihydro-1H-isoindole-1,3-dione

Participants

Reaction Steps

A mixture of 3-chlorocyclopentene (36.9 g), N-hydroxyphthalimide (58.2 g) and triethylamine (53.9 g) in acetonitrile (370 ml) was refluxed for 2 hours. The reaction mixture was poured into ice-water. The precipitated crystals were collected by filtration, washed with water and dried over phosphorus pentoxide to give N-(2-cyclopenten-1-yl)oxyphthalimide (56.5 g).
