Process for the preparation of ubihydroquinones and ubiquinones |
| abstract |
A process for the preparation of ubihydroquinones and ubiquinones by condensation of a prenol or isoprenol with a hydroquinone or derivative thereof in the presence of 0.005-1.0 mol % of a catalyst which is a Broensted-acid, a Lewis-acid from the group consisting of a derivative of Bi or In or an element of group 3 of the periodic table of the elements, a heteropolyacid, an NH— or a CH-acidic compound, and optionally oxidizing the ubihydroquinone obtained. |
