Abstract: (8) AE 3691 The invention relates to a process for the preparation of .alpha.-amino-.alpha.-methylcarboxylic acid amides and .alpha.-amino-.alpha.-cycloalkyl-carboxylic acid amides of the formula: where R1 represents alkyl, alkaryl, aryl, alkenyl, heteroalkyl or heteroaryl, whether or not substituted, R2 is methyl, or forms, together with R1, a cycloalkyl group, by conversion of the corresponding amino nitriles using hydrogen peroxide under basic conditions and is characterized in that the conversion takes place in the presence of ammonia. By preference 2-6 moles hydrogen peroxide and 3-12 moles ammonia are used per mole amino nitrile.
