Abstract
The reaction of aryl halides (1a–g) with octacarbonyldicobalt in the presence of methyl iodide and sodium hydroxide under phase-transfer conditions was found to give a mixture of aryl methyl ketones (2a–g) and aromatic carboxylic acids (3a–h). From vinyl halides (9a–c), however, the corresponding carboxylic acids (10a–c) were obtained exclusively.
