A Simple and Facile Carboxylation Method and Its Application for Synthesis of Liquid Crystals

Abstract

Sonication of a mixture of magnesium powder, 1,2-dibromoethane, aryl bromide and diethyl dicarbonate in THF followed by treatment with BF₃·OEt₂ at room temperature afforded aryl ester with reasonable yield. A series of aryl bromides were investigated and transformed to their corresponding aryl esters under the reaction conditions.

carboxylation - Barbier reaction - diethyl dicarbonate - Lewis acid - liquid crystal
