Faraone, G. and Cattalini, L. and Ricevuto, Vittorio and Romeo, Raffaello and Martelli , M. (2005) Effetto solvente nelle reazioni del trans-[Pt(piperidina)$_2$CI$_2$]CON CI Br. - Indagini radiochimiche e spet-trofotometiche. Accademia Peloritana dei Pericolanti Classe FF. MM. NN. , 83. pp. 19-29.
The kinetics for the substitution ractions of trans-$[pt(piperidin_2CI_2]$ with $Li^3^6 CI$ and $N(C_2H_5)_4Br$ using the solvents:$CH_3OH, C_2H_5OH,$ and $(CH_3)_2CO$ at different temperatures are reported. The kinetics were follwed with radiochemical and spectrofotometrical technique. The reactions occour according with the rate equation: $k_o_b_s=k_1+k_2[Y-]$. The ratio of the specific rates of the second order for the ractions with $Br-$ and $^3^6Cl-, k_2^B^r/k_2^3^6^C^l,$ decreasein the order $CH_3OH> C_2H_5OH> ter-C_4H_9OH,$ that is in the order of increasing the strie factors of the organic radicals. The reactivity of the two studied nucleophiles in $(CH_3)_2CO$ is higler than in the protic solvents.
