“…65, Verlag Chemie, Berlin, 1942, p 317. ^obsd * , * + * +[ -] (7) Here it is necessary to assume that the aquation reaction is much faster than substitution by phenan throline so that the equilibrium between MX42~a nd M(H20)X3~i s maintained throughout the kinetic run. When comparisons can be made with known aquation rates, the assumption has been shown to be justified.9 A few kinetic runs showed small deviations at the very beginning as the equilibrium was being established.…”

“…(5) can be explained in terms of equilibrium (9) where enH+ enters into reaction with the Pd(II) substrates while enH22+ appears to be nonreactive. The unreactive nature of fully protonated aliphatic amines toward Pt(II) [16,17], Au(II1) [10,11], and in this paper, Pd(I1) complexes, seems to be a common feature for substitution at the square planar center.…”

The activation energy parameters for the reaction of P d X P (X = C1-, Br-) in aqueous halide acid solution with thiourea (tu) and selenourea (seu) have been determined. High rates of reaction parallel low enthalpies and appreciable negative entropy of activation.The rate law in each case simplifies to /cobs = k[L] where L = tu or seu, and only liganddependent rate constants are observed at 25°C. The liganddependent rate constants for the first identifiable step in the PdCId2-+ X system is (9.1 f 0.1) X lo3 M-' sec-* and (4.5 & 0.1) X lo4 M-' sec-' for X = tu and seu, respectively, while for the PdBrr2-+ X system it is (2.0 f 0.1) X lo4 M-' sec-' and (9.0 f 0.1) X lo4 M-' sec-' for X = tu and seu, respectively.
