Water → cis-3,5-Diacetoxy-1-cyclopentene

Participants

Reaction Steps

One (1.0) g of cis-1,4-dibromocyclopent-2-ene, 3.5 g of potassium acetate, 0.7 g of cetyltrimethylammonium chloride, 5 ml of carbon tetrachloride, and 2 ml of water were used in the manner similar to the Example 1, at 42° C. for 6 hours. After addition of 30 ml of ether, the organic phase was dried over sodium sulfate, and the organic solvent was distilled off under a reduced pressure similarly to Example 1. Further subjecting the residual system to a reduced pressure distillation, 0.7 g of cis-1,4-diacetoxycyclopent-2-ene boiling at 60°-61° C./0.03 mmHg was obtained. The yield was 77%.
