Kolbe-couplings with cyclohexane General procedure: Carboxylic acids (2.5 mmol) were added to electrolyte solutions (20 mL) using potassium hydroxide as a supporting electrolyte (saturated) in the presence of the cycloalkanes. The undivided reaction cell was capped with a septum equipped with platinum electrodes (10 mm×20 mm). The electrolysis was then performed at constant current. After completion of the reaction, the cycloalkane phase was concentrated under reduced pressure and the residue was purified by silica gel column chromatography using n-hexane-EtOAc to give products. The products' yields were determined by NMR. |
