The formation of palladium(II) complexes with aliphatic amines and their oxidation by chloramine‐T in perchloric acid medium has been studied. The spectrophotometric studies showed the formation of 1:1 and 1:2 complexes between palladium(II) and amine in absence of HClO 4 . An increase in [HClO 4 ] in reaction mixture suppresses the complex formation and in presence of [HClO 4 ] ∼10 −3 mol dm −3 only a 1:1 complex between palladium(II) and amine has been observed. The effect of Cl − on the complex formation has also been studied. Palladium(II)‐catalyzed oxidation of these amines by chloramine‐T showed a first‐order dependence of rate with respect to each—oxidant, substrate, catalyst, and H + . The mechanism consistent with kinetic data for the oxidation process has been proposed in absence as well as in presence of initial [Cl − ]. © 2002 Wiley Periodicals, Inc.
