โœฆ Synopsis

Here we rleh to report on the preparation of 7-chloro-7-fluoronoroarane (I), 7ohloronoroarane (II) and 7-fluoronoroarane (III), ae well ae on their ring expansion reaction in quinoline at elevated temperature.

7-Chloro-7-fluoronoroarane (I) war prepared by adding 0.6 mole of methanol gradually to a mixture of 0.75 mole of cyolohexene, 0.6 mole of aodium hydride and 0.6 mole of methyl diohlorofluoroaoetate at room temperature. (1) The yield of the adduct ~88 6096, being the higheet one ever reported in the literature.

Although it has been fully established that endo-7-halonorcaranes undergo ring expansion reactions much faster than the corresponding exo-isomers, (1,293) SOme ambimity still remains on the relative reactivities of endo-and exo-7-halo-2-oxa--
