The present invention relates primarily to a process for preparing certain phosphorus-containing cyanohydrins of the formula (I), and also to certain phosphorus-containing cyanohydrins per se and to their use for the preparation of glufosinate and/or glufosinate salts. The present invention further relates to certain mixtures particularly suitable for preparing the phosphorus-containing cyanohydrins of the formula (I).

Process for preparing phosphorus containing cyanohydrins

The present invention relates to a novel catalytic hydrogenation of substituted 2-methyl cyanopyridyl derivatives, in particular 3-chloro-5-(trifluoromethyl)pyridin-2-yl]acetonitrile [=Py-CN] to substituted 2-ethylaminopyridine derivatives, in particular 2-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]ethanamine [=Py-ethanamine] or salts thereof in the presence of metal catalysts, in particular palladium catalysts.
