Synthesis of Heteroaromatic Carboxylic Acids by Carbonylation of Hetaryl Halides with Catalysts Based on Cobalt Carbonyl Modified with Epoxides

摘要

A new method for the synthesis of heteroaromatic acids and their derivatives (esters and salts) by carbonylation of the corresponding halides was developed. Hetaryl halides were activated in alcoholic-alkali medium by highly active catalytic systems based on cobalt carbonyl modified with epoxides, developed previously for carbonylation of aryl halides.
