Conclusions

  1. 1.

    The rate constants for the protodemercuration of di(1′-methoxy-1-ferrocenyl)mercury, 1-methoxy-1′-chloromercuriferrocene, di(1′-acetoxy-1-ferrocenyl)mercury, 1-acetoxy-1-chloromercuriferrocene, di(1′-methoxycarbonyl-1-ferrocenyl)mercury, and 1-methoxycarbonyl-1′-chloromercuriferrocene by hydrochloric acid have been measured in 90% (by volume) aqueous dioxane at four temperatures. The energies and entropies of activation have been calculated.

  2. 2.

    The protolysis of mercury derivatives of methoxyferrocene takes place approximately twice as fast and the cleavage of the mercury derivatives of acetoxy- and methoxycarbonylferrocene approximately 3 and 30 times more slowly than the protodemercuration of the unsubstituted compounds. The protolysis of unsymmetrical compounds takes place more slowly than that of the symmetrical compounds.
