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.
当 1,4-二芳基-4-甲基-1,3-戊二醇用二乙氨基三氟化硫处理以将氟原子引入中心连接时,具有 1-氟-1-甲基乙基的 1,2-芳基迁移产物为得到两种非对映异构体。利用这种迁移,制备了一些具有 1-氟-1-甲基乙基基团的非酯拟除虫菊酯。还讨论了其他氟化试剂的反应性。
