The influence of the carboxylate group upon the reactivity of theα- andβ-positions in the system of cyclopentadienylmanganesetricarbonyl in the reaction of protophilic substitution was studied.
The factors of the partial rates of isotopic exchange of hydrogen for theα- andβ-positions were found by a combination of methods of isotopic exchange of hydrogen and proton resonance.
Under these conditions, the reactivity of theα-position is almost three times as great as that of theβ-position.
