A CIDEP study of the addition of trialkylsilyl radicals to substituted p-benzoquinones

Evidence has been obtained through the combined ESR and CIDEP techniques for the two distinct pathways in which trialkylsilyl radicals add to substituted p-benzoquinones via the carbonyl oxygen as well as the ring carbon–carbon double bonds. The results represent the first observation of CIDEP from organic radicals containing an organosilyl group in solution.
