Abstract:
The calculation of the frequencies and forms of the vibrations of the molecule of (ClC3H4PdCl)2 (I) was
discussed in [1] and it was shown that the introduction of substituents into the fi-position of the π-allyl ligand
leads to a considerable change in the state of the Pd-allbond [1]. Examination of the force constants of this
bond (KPd-C) in the complexes discussed in [2-4] led to the view that the increase in the donor properties of
the allyl ligand leads to an increase in the strength of the Pd-all bond and to a decrease in its reactivity in the
structural incorporation ofbutadiene [1]. The criterion of the change in the state of the Pd-all bond was the force constant
KPd-C, obtained by finding the force field of the entire molecule, as described in [4]. The correctness of
this viewpoint can be verified only by examining a large number of complexes with p-substituents of different
electronegativity. For example, if it were possible to obtain the compound (FC3H4PdF)2 (II), then according to
the model being considered its molecule should have a minimum KPd-C and a maximum reactivity in the
structuralincorporation. For the molecule of (β-BrC3H4PdBr)2 (III), KPd-C should have a value intermediate
between that the complex (I) and the nonsubstituted π-allyl complex (C3H5PdCl)2 (IV).
The present paper gives the results of a calculation of the frequencies and forms of the vibrations of the
molecule of compound III.
