    • note
    • [25] Although the degree of folding of the salen ligands depends upon the nature of the apical ligand and the relative configuration of the complexes, both (R,R)- and (R,S)-complexes bend in a similar moderate degree when they bear an aprotic donor ligand. Based on this study, we assumed that both (R,R)- and (R,S)-intermediate carbenoid species bearing NMI at their apical site would adopt a moderately folded stepped-conformation.

    • It is reasonable to consider that carbenoid species derived Co-salen complexes bearing a bulky substituent at C3 and C3′ do not allow substrate-approach from the C3 and C3′ side because of the short distance between the C3 and C3′ substituents
