Abstract

A Kinetic study of the reaction between [Pt (dipy) (Am) X]+ and $CH_3O^-$ in methanol at 35°C is reported. The kinetic rate law of the process is: $k_o_b_s = k_1 + k_2 . [CH_3O^-] .$ The Kinetic term $K_1$ is interpreted assuming an attack of the alchoolic group on Am on the Pt (II). The $k_2$ term is interpreted considering a rapid acid-base preequilibrium, followed by the rate determining displacement of the halide ion by the alkoxide group. The effect of the length of the chain (Am) and that of the leaving-group are also reported.
