Abstract
When 1,4-diaryl-4-methyl-1,3-pentanediol was treated with diethylaminosulfur trifluoride to introduce fluorine atoms into the central link, 1,2-aryl group migration products which have a 1-fluoro-1-methylethyl group were obtained as two diastereomers. Utilizing this migration, some non-ester pyrethroids possessing a 1-fluoro-1-methylethyl group were prepared. The reactivity of other fluorinating reagents is also discussed.
