Abstract

• E.s.r. spectra have been recorded in solution for the substituted cyclopentadienyl radicals X3MC5H4., where X3M = Me3Si, Me2HSi, Me2ClSi, Me2FSi, Ph2ClSi, Cl3Si, Me3Ge, Bu3Ge, Ph2ClGe, and Me3Sn. The spectra can be interpreted in terms of perturbation of the orbitals ��A and ��S which are degenerate in the C5H5. radical. This allows the substituents to be placed in the following sequence regarding their electronic interactions, compared with that of hydrogen, with the ��S MO of the cyclopentadienyl ��-system: electron repelling, Me3C ��� Bu3Ge ��� Me3Ge > H; electron attracting, H < Me3Sn < Me3Si < Me2HSi < Me2ClSi < Ph2ClGe < Me 2FSi < Ph2ClSi < Cl3Si.
