摘　　要：以 MN P为捕集剂 ,对三种水合丁基钴肟 RCo( DH) 2 H2 O( R=n- C4H9,i- 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 .The radicals formed from the anaerobic photolysis of aqua(alkyl)cobaloxime(R=nC 4H 9 , iC 4H 9 , secC 4H 9) are detected by the EPR spin 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—C bonds cleavage under photolysis are converted into the secondary ones.
