Abstract: The radicals formed from the anaerobic photolysis of aqua(alkyl)cobaloxime(R=n-C4H9, i4H9, sec-C4H9) are detected by the EPRspin trapping technique using 2-methyl-2-nitroso-propane as the spin trap. The rearrangement reactions are found in which the primary radicals produced by Co-Cbonds cleavage under photolysis are converted into the secondary ones.

Key words: Aqua(alkyl)cobaloxime, EPR, Spin trap, Radical rearrangement
