The Ag(I)-catalysis of Ce(IV)-amine reaction is explained in terms of a 1 : 1 complex formation between Ag(I) and amine which later reacts with Ce(IV) bimolecularly to give the products. The rate law for the Ag(I)-catalysed oxidation of amines was sound to be -\(\frac{d[Ce(IV)]}{dt}\)=\(\frac{kK(Ce(IV)][amine][Ag(I)]}{1+K[amine]+K[Ag(I)]}\) Ammonia and the corresponding aldehyde or ketone were identified as the products of oxidation of aliphatic primary amines, while formaldehyde and other amines were the products when dimethyl or trimethyl amities were the substrates. The activation parameters for the oxidation of amines are presented and discussed.
