    • The sum of the internal bond angles for a formal 6-membered ring connected through Si(1)-C(1)-C(2)-C(3)-C(4)-Si(2) is 718.8° Reverse signed magnetic shielding computed at 1 Å above the ring center as a probe of aromaticity, see:

    • The theoretically optimized structure of the less hindered model, 1,2-diphenyl-1,2-disilabenzene, exhibits completely planar structure with C(Ph)-Si-Si-C(Ph) torsion angle of 0°, suggesting the trans-bent structure of 2 would be due to the severe steric repulsion of extremely bulky Bbt groups When a Bbt group is connected directly to a chiral center, the two trimethylsilyl groups at the ortho-benzyl position are in diastereomerically non-identical situation in NMR spectroscopy, see ref.3a
