Title:
METHOD FOR PREPARING CYCLIC SULFONIC ACID ESTER COMPOUND
Document Type and Number:
WIPO Patent Application WO/2022/092834
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing a cyclic sulfonic acid ester compound and has an effect of providing an economical method for preparing a cyclic sulfonic acid ester compound, in which by using a cyclizing agent alone under a catalyst-free condition, mass production is possible with high purity and high yield, and a reaction process is simple.
