Stereo- and regiocontrolled synthesis of fluorohydrins from optically active epoxides

The hydrofluorination of optically active terminal epoxides, which were produced by a microbial reaction, with HF-amine reagents weer studied. 1,2-Epoxyoctane and glycidyl hexyl ether gave the corresponding 2-fluoro-1-alkanol derivatives with inversion of the asymmetric center with high stereospecificity, while in the hydrofluorination of pentafluorostyrene oxide and 2-methyl-1,2-epoxyhexane, partial racemization occurred. The basicity of the amine used, the HF/amine ratio in the HF-amine reagent, and the substituent on the epoxide affected the stereospecificity and regioselectivity of the hydrofluorination of the epoxides.
Liquid crystal materials, mixtures and devices

Liquid crystal compounds of formula I may be used by themselves or they may be mixed with other liquid crystal compounds to give useful liquid crystal mixtures which may then be used in liquid crystal devices. The materials exhibit smectic mesophases and may therefore be used in ferroelectric, ferrielectric, antiferroelectric, themochromic and electroclinic devices. They may also be used as long pitch materials.
