Impact of the corrin framework of vitamin B12 on the electrochemical carbon-skeleton rearrangement in comparison to an imine/oxime planar ligand; tuning selectivity in 1,2-migration of a functional group by controlling electrolysis potential

To probe the mechanism of a model reaction for an enzymatic carbon-skeleton rearrangement, an alkyl bromide substrate having two different migrating groups on the β-carbon (phenyl and carboxylic ester groups) was applied to electrolysis mediated by a hydrophobic B12 model complex in this study.156
