    • Because separation of these stereochemical isomers was difficult, the isomeric mixture was employed for the hydrogenolysis reaction. The reaction completely proceeded but the hydride species corresponding to the minor species was not observed at all

    • One of the ortho methyl resonances in 9d appears in significantly high field at δ 1.57, while another ortho methyl group resonates at the comparable region to the related cis-bis 2, 6-dimethylbenzenethiolato ruthenium II complexes such as 2a δ 2.11, 2b δ 2.46, 2d δ 2.55, and free 2, 6-dimethylbenzenethiol δ 2.48. Because 9d is a coordinatively unsaturated complex, this fact may be caused by the lone pair electrons on the S atom attached to the saturated Ru center, or the ring current effect of the aromatic ring
    • One of the ortho methyl resonances in 9d appears in significantly high field at δ 1.57, while another ortho methyl group resonates at the comparable region to the related cis-bis (2, 6-dimethylbenzenethiolato) ruthenium (II) complexes such as 2a (δ 2.11), 2b (δ 2.46), 2d (δ 2.55), and free 2, 6-dimethylbenzenethiol (δ 2.48). Because 9d is a coordinatively unsaturated complex, this fact may be caused by the lone pair electrons on the S atom attached to the saturated Ru center, or the ring current effect of the aromatic ring.
