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.
