  Bromofluorination of bis(allyl)polyoxyethylene glycol ethers

  摘要：

  The bromofluorination of bis(allyl)polyoxyethylene glycol ethers has been achieved by action of N-bromosuccinimide/triethylamine trishydrogenfluoride. For the starting 2-methylallyl ethers, the addition reaction is regioselective and only tertiary fluorine adducts were observed. Under the same conditions a mixture of addition and degradation products was observed from the nonbranched bis(allyl) ethers. (C) 2000 Elsevier Science S.A. All rights reserved.

  compounds toward alkali metal cations than trans isomers possibly because of the potential cooperative coordination of two electron-donating sidearms. All trans isomers showed almost the same stability constants toward Na+ and K+. On the other hand, in the case of cis isomers, the difference in the position of the two sidearms on the crown ring was found to remarkably affect the complexation properties toward

  Several bis(bromomethyl) dimethyl 15-crown-5, 18-crown-6, and 21-crown-7 were prepared according to two methods without protecting reactive bromo substituents. Cis and trans isomers of la are separated and the structures are inferred by considering the complexation property of their derivatives having electron-donating sidearms toward sodium and potassium cations.
