Fluorinated five-to seven-membered cyclic ethers were stereoselectively synthesized from four-to six-membered cyclic ethers having an iodoalkyl substituent by fluorinative ring-expansion reaction using p-iodotoluene difluoride.
The synthesis of some 6-, 7-and &membered heterocycles through a base induced ring expansion of quaternized thiazolium, oxazolium and selenazolium salts is described. During studies of base-induced rearrangements of quaternized 5-(w-chloroalkyl)-thiazoles and oxazoles, -165OC) in 20-25% yield. Mass
