Summary

It was shown, by analyzing HFS in the EPR spectra of various metal ketyls, that the stabiliry of free radicals of the given type is determined by different factors. In aromatic metal ketyls the stabilizing factor is the considerable delocalization of the unpafred electron. In aliphatic metal ketyls the unpaired electron is mainly localized on the carbonyl carbon, and steric factors are more important than delocalization. In mixed ketyls of the type of trimethylacetophenone and benzoylferrocene K-ketyls, both factors act to a commensurable degree.
