Abstract

Abstract: The reaction of molecular oxygen insertion into Co—C bond of RCo(Salen)L(R=CH₃, C₂H₅,n-C₃H₇,n-C₄Hg and i-C₄H₉,L=N₂Oor Py)complexes under photochemicalconditions was studied by HPLCand UV-Vis spectrophotometry and the resulting productswere characterized by elementary analysis,IR,UV-Vis, ESI-MSand ¹H NMRspectra. Theresult shows that the insertion reaction of the oxygen into Co—C bond occurs and the prod-ucts are ROOCo(Salen)Lcomplexes which can be reduced to alcohols by NaBH₄ in THFandbenzene. The further studies on kinetics and mechanisms of the reaction are proceeding.
