Synthesis of aromatic carboxylic acids by carbonylation of aryl halides in the presence of epoxide-modified cobalt carbonyls as catalysts
A new procedure was developed for synthesis of aromatic and heteroaromatic acids and their derivatives (esters, salts) by carbonylation of the corresponding aryl halides. The acids are selectively formed in a high yield under very mild conditions. Highly active catalytic systems, base-containing alcoholic solutions of cobalt carbonyl modified with epoxides, were used to activate aryl halides. 2005 Pleiades Publishing, Inc.

An Observation on Carboxylation of 4H-Cyclopentaphenanthrene
Photocarboxylation of 4H-cyclopentaphenanthrene by carbon dioxide in the presence of N,N-dimethylaniline in dimethyl sulfoxide afforded 8,9-dihydro-4H-cyclopentaphenanthrene-8- and 2-carboxyl acid, and 4H-cyclopentaphenanthrene-8-carboxylic acid.These acids were derived into methyl-4H-cyclopentaphenanthrenes.
