| dc.description.abstract | The phenoxachalcogeninens were studied as donors toward tetracyanoethylene as the acceptor. It was found that values of K, ε[subscript C], ΔH, ΔG, and ΔS for the series show no significant change when the chalcogenine atom is varied from Te to 0. For the series of complexes studied, K has a value of about 1 or 2, ΔH is about -2.0 ± 0.4 kcal, ΔG is 0.0 ± 0.6 kcal, and ΔS is about -7.0 eu. ε[subscript C] varies from the approximate values of 1100 for the phenoxatellurine complex 200 for the diphenylene dioxide complex. The lack of significant changes in the thermodynamic values for the phenoxachalcogenine complexes with tetracyanoethylene were explained on the basis of a π-π interaction. This conclusion is different than that reached by Hetnarski and Grabowska³� in their study of the phenoxachalcogenine complexes with 1,3,5-trinitrobenzene as the acceptor. They attribute the small changes involved as being due to an n-type interaction in the case of phenoxatellurine, phenoxaselenine, and phenoxathiin, but the case of diphenylene dioxide, they propose a π-type donation. ... | en |
