    • Calculations for 5 are for the (R,R) configuration shown in Scheme 3, and drawings, torsion angles, and discussion will be in terms of this enantiomer, but experimental results are in fact for racemic 5a-f.

    • A referee has pointed out that the dielectric constant of dichloromethane is given as 9 at 293 K and 16 at 180 K in the CRC Handbook, so the improved agreement with experiment may be valid, but it is not clear whether solvent can dominate the dielectrics within a single molecule.

    • In compound 1a, calculations suggest that the maximum and minimum separation of two hydrogen atoms H-C-Si⋯C4-H is 9.04 and 6.25Å in the equatorial conformation, whereas these limits are only 8.00 and 5.92 Å in the axial conformation.
