Normally liquid, omega-hydrofluoroalkyl ether compounds (and selected mixtures thereof) have a saturated perfluoroaliphatic chain of carbon atoms interrupted by one or more ether oxygen atoms. The compounds can be prepare, e.g. by decarboxylation of the corresponding fluoroalkyl ether carboxylic acids and are useful, e.g., in cleaning and drying applications.
C8F17C6H4CHO, C8F17C6H4CO2H, C8F17C6H4COCOC6H5, and C8F17OCF2CF2C6H4COCOC6H5 proceeded readily. No C8F17OCF2C6H4COCOC6H5 was produced from the reaction of C8F17OCF2I with 4-iodobenzil in the presence of copper bronze. Low yields of bridged bisbenzils were obtained from the coupling reactions of ICF2CF2O(CF2)5OCF2CF2I and I(CF2CF2O)5CF2CF2I with 4-iodobenzil. Based on by-products formed, the operative
