Abstract
A study has been carried out of the conformations of triisopropyl(aryl)silanes (i-Pr)(3)SiAr, (Ar = phenyl, 1-naphthyl, and 2-naphthyl) both as to the orientation of the three isopropyl groups and the conformation about the silicon-aromatic bonds. The report comprises dynamic NMR studies of conformational interconversions in solution and in the solid state as well as molecular mechanics calculations. The barriers for the stereomutation processes measured in the crystalline state were found significantly higher than those in solution.
