Synthesis and Properties of Aromatic Compounds

Several epimeric alkyl-substituted 1,3-oxathianes have been chemically equilibrated. The equilibrations and some compilations yielded values for the conformational energies of axial methyl, ethyl and isopropyl groups on position 2, and values for the conformational energies of axial methyl groups on positions 4, 5 and 6. These results are discussed in comparison with the corresponding data for 1,3-dioxanes and 1,3-dithianes.
