Stoelevik, Reidar published the artcileConformational analysis of 1,2-dihalotetramethylethanes and 1,2-dihalotetramethyldisilanes by molecular mechanics calculations, Computed Properties of 594-81-0, the publication is Journal of Molecular Structure (1989), 131-5, database is CAplus.
By using nonbonding atom···atom interaction potentials derived from gas-phase data on related haloalkanes, torsional potentials of the title mols. are calculated These mols. have stable anti and gauche conformations. In all mols. the anti has a lower energy than the gauche. The rotational barrier heights corresponding to a transition from gauche to anti are 0.5-1.5 kcal mol-1 in the disilanes and 3.5-5.5 kcal mol-1 in the ethanes. Calculated results are compared with the gas-phase observations on the disilanes.
