| Research Abstract |
Hydrogenation of an alkene is quite important for organic' syntheses employing a catalyst (Pd, Ni, Pt) which chemisorbes active hydrogen, however, hydrogenolysis of allylic C-O bonds and benzyloxy groups (Bn-O-) also takes place under the same conditions. Therefore, it is difficult for alkenes having an allyloxy and/or benzyloxy group to be hydrogenated by active hydrogen without the hydrogenolysis.
A new hydrogenation system utilizing electrochemically produced activehydrogen has been successful in the saturation of several unsaturated organic compounds such as styrene and its derivates.
The reaction cell is made up of two compartments separated by a Pd sheet as cathode, where galvanostatic electrolysis of water is carried out to produce the active hydrogen atone side of the Pd sheet, and a substrate is hydrogenated at the opposite side surface by active hydrogen permeating through the Pd sheet.
