phases, Cyclodex® G-TA, is found to be a chiral shift reagent for several of the fluoroethers. A rough correspondence is found relating the enantiomeric separation factor of a fluoroether and the chemical shift differences between its 1H and 19F nuclei in the NMR spectrum. Based on this data, it is proposed that a simple NMR experiment can screen chiral stationary phases prior to a desired gas chromatographic

Synthetic methods, especially those that use brominetrifluoride as a fluorinating agent, are described for the preparation of a number of fluorinated ethyl methyl ethers in good yield and high purity. In all cases, medium-scale syntheses (8–22 g) of potentially anesthetic compounds have been accomplished. The compounds are of sufficient purity (>99%) for biological evaluation.
