| Description |
The use of Ti/ceramic TiO2 cathode as an effective
cathode material for the reduction of two ketones—
cyclohexanone and benzalacetone (BA) are highlighted.
Galvanostatic reduction of these ketones gave exclusively
cyclohexanol and benzyl acetone (4-phenyl 2-butanone) as
the corresponding hydrogenated products, as characterized
from their boiling points and nmr spectra. Higher product
yields were observed as compared to the reduction of the
ketones at conventional cathode materials like lead under
identical experimental conditions. Best conditions for the
formation of products have been identified based on current
density, temperature and acid strength. Cyclic voltammetry
indicates a mechanism involving heterogeneous redox catalysis
involving the surface fixed redox groups Ti4+/Ti3+. The
reaction can be conveniently scaled up.
