The thermal reaction between N-tert-butyl-α-phenylnitrone (PBN) and trichloroacetonitrile is promoted by acids HA, giving spin adducts A-PBN. and CCl2=C=N-PBN., presumably via addition of HA to the nitrone with formation of a hydroxylamine and oxidation of the latter by trichloroacetonitrile (the Forrester-Hepburn mechanism).

An overview of application of spin trapping to electrochemical investigations is presented.Cited studies include characterizations of primary electrode reaction products (e.g., electrooxidations of halide and pseudohalide species, electroreduction of N-methylpyridinium ion) as well as the identification of transient intermediates arising from homogeneous reactions which are electroinitiated.The validity of spatially resolved spin trapping as a probe in the investigation of interfacial processes is demonstrated with examples drawn both from the previously reported covalent attachment of nitrone derived spin traps to silaceous surfaces and from recent studies of spin trapping in micelle and vesicle systems.Amphiphilic nitrone spin traps have been shown to coassemble with both micelles and vesicles such that the nitrone functionality resides in the interfacial region of the ordered system.The ability of these interfacially localized nitrones to trap transient radicals generated both in the hydrophobic domain of the micelle or vesicle and in the aqueous exterior domain is demonstrated.

Azidyl, cyanatyl, and cyanyl radicals and chlorine atoms have been detected by spin trapping using α-phenyl-N-tert-butyl nitrone (PBN) in the monoelectronic electrooxidations of azide, cyanate, cyanide, and chlorine.Azidyl and cyanatyl radicals were also detected with PBN in the persulfate oxidations of azide and cyanate.Azidyl radicals could be detected in the reaction of azide with hydroxyl radicals in the presence of PBN.
