The reaction between carboxylates and hexachloroosmate(V) has been investigated. For carboxylates, RCOO–, corresponding to radicals R• which are difficult to oxidize (with Ei larger than ∼9 eV), the reaction gave one-electron oxidation products, as typified by the formation of C-to-N coupling products in good yield from tert-butylcyanoacetate ion. The kinetics of the reaction between the hydrogendiacetate ion and OsCl6– in acetonitrile was studied in more detail and found to conform to a kinetic model involving a second-order electron-transfer step between acetate ion (existing in equilibrium with acetic acid and hydrogen-diacetate ion) and OsCl6–. Attempts to trap R• from the carboxylate/hexachloroosmate reaction by α-phenyl-N-tert-butylnitrone (PBN) led only to the formation of acyloxyl spin adducts, presumably via the reaction between PBN•+ (formed by one-electron oxidation of PBN by the osmate) and the carboxylate ion. Other nucleophiles underwent the same type of reaction, previously denoted inverted spin trapping, and also the more oxidation-resistant spin trap 4-NO2BPN was shown to possess this type of reactivity.
