Title:
NOVEL SYNTHETIC METHOD FOR 1-ACETYL-1-CHLOROCYCLOPROPANE
Document Type and Number:
WIPO Patent Application WO/2022/100711
Kind Code:
A1
Abstract:
An environmentally-friendly and efficient novel synthetic method for 1-acetyl-1-chlorocyclopropane. Under the promotion effect of a ionic liquid, a raw material 3,5-dichloro-2-pentanone is subjected to a ring-closure reaction under alkaline conditions to produce the 1-acetyl-1-chlorocyclopropane. The synthetic method can be carried out in the presence or absence of other solvents, and at the same time, the ionic liquid can also be recycled for use. Therefore, the synthetic method is environmentally-friendly and low in cost, and has a very high industrial production value.
