Electroreduction of organic compounds. 28. Partial Hydrogenation of Polycyclic Aromatic Hydrocarbons by electroreduction in protic solvents
摘要:
Polycyclic aromatic hydrocarbons (PAH) such as anthracene (1), phenanthrene (5), acenaphthylene (15), pyrene (17), chrysene (22), and fluoranthene (28) are selectively hydrogenated upon electroreduction at a lead cathode in ethanolic solution. The degree of hydrogenation and the structure of the products depend on the reaction conditions, in particular on the applied reduction potential.
