摘要: Abstract Substitution reactions of the type Pd(R5dien)- H2O2+ + I−→ Pd(R5dien)I+ H2O (R = H, Me and Et) were studied as a function steric hindrance in range 7⩽pH⩽12 order to solve problems related nature such basic medium. All kinetic data can be interpreted terms an anation model which aqua complex is only reactive species this pH range. No evidence for conjugate base formation or participation hydroxy bridged was found. Deviations at > 9 accounted increase fraction resulting from reverse aquation contribution iodo under conditions.
