Abstract
A process is described for the preparation of oxamide derivatives wherein one or both --NH.sub.2 groups are replaced by primary or secondary amino groups, through reaction of oxamide with a suitably selected amine of formula RR.sup.1 NH wherein R represents a substituted straight or branched (C.sub.2 -C.sub.12)alkyl radical wherein the substituent(s) or at least one of the substituents is selected from the group consisting of hydroxy, amino, mono-substituted amino, and di-substituted amino, and R.sup.1 represents hydrogen or an optionally substituted (C.sub.1 -C.sub.6)alkyl radical; representative oxamide derivatives which can thus be obtained useful as corrosion inhibitors, intermediates for polymers, polymer stabilizers, and slow-release fertilizers, are also described.
