The stereochemistry of substituted 2-vinyl-2-methyl-1,3-dioxa-2-silacyclohexanes was studied by H-1 and C-13 NMR spectroscopy. The configurational and conformational assignment of it mixture of 2-vinyl-2,4-dimethyl-1,3-dioxa-2-silacyclohexane diastereorners with various ratios of the cis and trans forms was made. The molecules of both conformers occur chiefly in the chair conformartion with equatorial location of the methyl group at the C-4 atom. The experimental data were confirmed by AM1 and MM+ optimization of the molecular geometry.
