Photoinduced and N-Bromosuccinimide-Initiated Esterification of Aromatic acids and Terminal Alkynes with Alcohols

Abstract

A mild and convenient protocol for the esterification of aromatic acids and terminal alkynes with alcohols by visible-light catalysis strategy using N-bromosuccinimide (NBS) as additive has been developed. This protocol provides access to substituted aromatic esters and α-ketoesters in moderate to good yields at room temperature. The advantage of this method is its operational simplicity compared to other known methods.

Keywords
