tetraethyleneglycol [FO5] or pentaethylene glycol [FO6] and in the reaction of 1-(bromomethyl)-3-methyl-2-fluorobenzene with aza-15-crown-5 [FNO4]. The analogous reactions of 1,3-bis(bromomethyl)benzene with diaza-18-crown-6 [HN2O4], diaza-15-crown-5 [HN2O3], and the potassium salt of tetraethylene glycol [HO5] led to the isolation of closely related fluorine-free cryptands and crown ethers. The 19F NMR resonances of
