Graphical Abstract

Cobalt-substituted cyclopropanes could be of significance in coenzyme B12-catalyzed rearrangements. Interestingly, a cobaloxime generated in situ reacts only with the exo bromide (2) and not with the endo bromide (1) to give product (3). The retention of configuration observed in this reaction is probably due solely to shielding by the dihydrophenanthrene flank.
