Insertion of Diphenylboron Group to the Cobaloxime Moiety

In the molecular structure of I after the photo-irradiation, the produced 1-ce group does not take a disordered stracture with R and S configurations. Since the crystal has a center of symmetry, the molecule at the inverted site has the opposite configuration. The molecular structure of A in n after the photo-irradiation showed nearly the same structure although the occupancy factor of the photo-produced 1-ce group became 0.30. The molecular structure of B has the inverted structure to A after the photo-irradiation. 

The structural changes of the 2-ce groups in I and HA during the photo-irradiation are shown in Fig. 6.1 la, b, in which the molecules are viewed normal to the cobalox-ime plane. The molecule HB is the mirror image reflected by a plane perpendicular to the cobaloxime plane, passing through the cobalt and boron atoms, hi order to explain the reason why one enantiomer of 1-ce group is made at a site, the reaction cavities for
