Abstract

Reaction of heptamethyl cob(I)yrinate with 1',6'-dichloro-1',6'-dideoxy-beta-D-fructofuranosyl-4-chloro-4-deoxy-alpha-D-galactopyranoside (sucralose) gave an alkylcobyrinate, heptamethyl-6'-[alpha-D-galactopyranoside- 1'-chloro-1',6'-dideoxy-beta-D-fructofuranosyl-4-chloro-4-deoxy]cobyrinate perchlorate, [(Suc)Cob(III) 7C(1)ester]ClO4. Cleavage behavior of Co-C bond of the alkylcobyrinate was investigated under various conditions (hv, H+ and reduction) using UV-vis spectroscopy combined with the EPR spin-trapping technique, and by cyclic voltammetry.
