Abstract

The reactions of cobalt(II) tetrasulphophthalocyanine, [Co^II(tspc)]^4- with ^.CH₃, ^.CH₂CH₂OH, ^.CH(CH₃)CH₂OH, ^.CH(CH₃)CH(CH₃)OH and ^.CH₂C(CH₃)₂OH free radicals have been studied. The results indicate that the first product formed in these reactions has the form [Co^II- (tspc-R)]^4-, where R is the aliphatic free radical, the exact nature of the bonding of ^.R to tspc is not clear. The complex [Co^II-(tspc-R)]^4- rearranges into [(tspc)Co^III-R]^4- in a process obeying a first-order rate law. [(tspc)Co^III-CH₃]^4- decomposes into [Co^III(tspc)]^3- + CH₄, whereas the complexes [(tspc)Co^III- CR₁R₂CR₃R₄OH]^4- decompose into [Co^III(tspc)]^3- + R₁R₂C=CR₃R₄+ OH^-.
