摘要： 以MNP为捕集剂,对三种水合丁基钴肟RCo(DH)2H2O(R=n-C4H9,#em/em#-C4H9,sec-C4H9)水溶液进行了光解EPR研究,发现其Co-C键断裂产生的自由基进一步重排的反应.

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
