ملخص

The reaction of cobalt(II) tetrasulfophthalocyanine, [Co^II(tspc)]^4-, with ·CH₂C(CH₃)₂OH free radicals was studied. The results indicate that the first product formed is [(tspc)Co^IIICH₂C(CH₃)₂OH]^4-. This product loses water via β elimination to yield [(tspc)Co^III,CH=C(CH₃)₂]^4-. The decomposition of the latter compound yields [Co^ICtspc)]^5- + OCHCH(CH₃)₂ at pH 9.5, [Co^III(tspc)]^3- + CH₂=C(CH₃)₂ at pH ~6, and mainly [Co^II(tspc)]_4- plus equal amounts of CH₂=C(CH₃)₂ and OCHCH(CH₃)₂ at pH ~3. The results suggest that a pK of the water molecule trans to the aliphatic residue affects the mechanism of hydrolysis. A further reaction is observed, the exact nature of which is not fully understood. For comparison purposes the oxidation of [Co^II(tspc)]^4- by [formula-omitted] and its reduction by [formula-omitted]. were studied.
