The reaction of molecular oxygen insertion into Co C bond of RCo(Salen)L(R=CH_3, C_2H_5,n-C_3H_7,n-C_4Hg and i-C_4H_9,L=N_2Oor Py)complexes under photochemicalconditions was studied by HPLC and UV-Vis spectrophotometry and the resulting productswere characterized by elementary analysis,IR,UV-Vis, ESI-MS and ￣1H NMR spectra. Theresult shows that the insertion reaction of the oxygen into Co C bond occurs and the prod-ucts are ROOCo(Salen)L complexes which can be reduced to alcohols by NaBH_4 in THF andbenzene. The further studies on kinetics and mechanisms of the reaction are proceeding.
