| titleOfInvention | Process for preparing symmetrical and unsymmetrical N,N-dihydrocarbylhydroxylamines |
| abstract | A process for preparing N,N-dihydrocarbylhydroxylamines of the general formula (I) n n nwhere R 1 , R 2 , R 3 and R 4 are selected independently from among hydrogen, aliphatic, cycloaliphatic, heteroaromatic and aromatic radicals, or R 1 and R 2 and/or R 3 and R 4 are joined to form a ring, and not more than one radical among R 1 , R 2 , R 3 and R 4 is hydrogen, which comprises the steps a) reaction of hydroxylamine H 2 NOH or a salt of hydroxylamine with a compound of the general formula (II) or (III) n n nwhere R 1 , R 2 , R 3 and R 4 are as defined in formula (I), b) hydrogenation of the compound formed in step a) in the presence of a catalyst, c) further reaction of the compound formed in step b) with a compound of the general formula (II) or (III) and hydrogenation of the reaction mixture in the presence of a catalyst and d), if appropriate, reaction of the salt of the dihydrocarbylhydroxylamine formed in step c) with a base. |
