Title:
PRODUCTION METHOD FOR ETHER, ESTER, AND THIOETHER
Document Type and Number:
WIPO Patent Application WO/2012/077456
Kind Code:
A1
Abstract:
Provided is a method for simple, high-yield synthesis of ether, ester, and thioether that have a variety of functional groups. Specifically provided is a production method for ether, ester, or thioether, characterized by the reaction of an alkylating agent and a compound with a hydroxyl group or a thiol group, in the presence of a tertiary amine.
