from esters of 10-undecenoic acid using Olah's reagent yields predominantly the 10-fluoro-1 1-hydroxy derivatives, while the other regio isomers are obtained predominantly with mixtures of triethylamine trishydrogen fluoride and other amines. The best yields and best regioselectivity for the 11-fluoro-10-hydroxy compound, however, are found in conversion of the epoxide with potassium hydrogen difluoride/18-crown-6
