Studies on the production and disociation of coenzyme b~12 models by electrochemistry and spectro-electrochemistry.I.

The reaction of cobalt tetraphenylporphyrin (CoTPP) with PhCH2Cl is studied by electrochem. and spectroelectrochem. The results show that the essential condition for forming the s cobalt-carbon bond-contg. models is the central cobalt in cobalt-porphyrin reduced to lower valence (such as +1). The relation between the formation and dissociation of cobalt-carbon bond and elec. potential is discussed in detail and the mechanism of reaction of CoTPP with PhCH2Cl is also described.
