Perchloro(1-indenyl) and Perchloro-1-indenyl Radical
Abstract
The synthesis of perchlorobis(1-indenyl) (2) is presented and its thermal behavior described. The perchloro-1-indenyl radical (3), in equilibrium with its dimer 2, has been detected by ESR spectroscopy. From a study of this equilibrium, the dissociation energy of 2 has been calculated to be 20.83 kcal.mol-1.

It is shown that the very large variations in the CH and CC homolytic bond-dissociation energies for a large variety of organic compounds can be rationalized in terms of the stabilization energies of these species and their corresponding radical(s). In most cases, these stabilization energies can be explained completely by the electronic effects of substituents without referring to steric strain.
