抄録

The electrocatalytic hydrogenation of the title compound was examined over Raney Ni, Raney Co, Pt-carbon and Pd-carbon as hydrogen-active powder electrodes. A high conversion of ketone to alcohol was observed on the Raney catalysts when the pKa values of the proton sources employed were around 5. The metal-on-carbon catalysts showed a relatively low conversion of ketone regardless of the proton sources. The stereochemistry of the reaction was examined.
