Process for producing hydrogen or heavy hydrogens, and hydrogenation (protiation, deuteration or tritiation) of organic compounds using same
An object is to provide a process for providing hydrogen or heavy hydrogens conveniently without the necessity of large-scale equipment and a process capable of performing hydrogenation (protiation, deuteration or tritiation) reaction conveniently without the use of an expensive reagent and a special catalyst. The production process includes a process for producing hydrogen or heavy hydrogens, containing subjecting water or heavy water to mechanochemical reaction in the presence of a catalyst metal, and a process for producing a hydrogenated (protiated, deuterated or tritiated) organic compound, containing subjecting an organic compound and water or heavy water to mechanochemical reaction in the presence of a catalyst metal.

Process for making flavor and fragrant compounds
The present invention relates to the production of aromatic hexanols and compositions containing them. In particular provided herein are methods of producing hexenols comprising: a) contacting a hydroperoxide of a polyunsaturated fatty acid with a modified hydroperoxide lyase to form a hexenal; and b) reducing the hexenal to a hexenol in the presence of a hydride donor, a ketoreductase, and a co-factor wherein the contacting and reducing steps are carried out at essentially the same time in the substantial absence of baker's yeast.
