چکیده:
چکیده انگلیسی: The kinetics and mechanisms of the substitution reactions of trans-[Co(en)₂CNCl]⁺ with unidentate anions, , CN¯, I¯, , Br¯ and SCN¯ in 60% v/v DMF-H₂O binary solvent at 40.0±0.2 °C were studied spectrophotometrically. An I_d mechanism was assigned for the replacement of chlorine by , CN¯ and I¯, an I_a one for the entry of and SCN¯, and a D mechanism for Br¯ entry. Comparing the interchange rate constants, k_i, values has led to the following trend of reactivity of the anions toward the given substrate: The replacement of chlorine by the anions proceeded with a complete retention of configuration.
