| abstract |
The present invention relates to a process for preparing amines of formula (I)wherein R1 represents optionally branched C1-C12-alkyl, C3-C8-cycloalkyl, C6-C12-aryl or C6-C12-aryl substituted with halogen-and/or C1-C12-alkyl, C7-C10-aralkyl or C7-C10-aralkyl substituted on the aryl radical by halogen and/or C1-C12-alkyl, or an aldose residue of the formula CiH2i+1Oi in which i is 2 to 5 and wherein one hydrogen of the aldose residue is optionally replaced by a saccharide residue,by catalytically hydrogenating aldehydes of formula (II)wherein R1 has the meaning indicated for formula (I), in the presence of ammonia, a hydrogenation catalyst, and disodium tetraborate. |
