3-oxathianes, newliquidcrystal compounds, were synthesized by the acetalformation reaction of the corresponding aldehydes and 2-alkyl-3-mercapto-1-propanols. The mesomorphic behaviors of these 1,3-oxathiane compounds were compared with those of the corresponding 1,3-dithianes and 1,3-dioxanes. Some of 2-(p-cyanophenyl)-5-alkyl-1,3-oxathianes exhibit monotropic nematic liquidcrystal phase at room
