The reaction of alkoxide ions with some chlorine-substituted norbornadienes

Abstract

The reaction of 1,2,3,4,7,7-hexachloro-5-phenylnorborna-2,5-diene with methoxide ions results in the addition of methanol to the phenyl-substituted double bond. 2,3,4,5-Tetrachlorobiphenyl, previously reported to be the reaction product, could not be detected. The reaction of ethoxide ions with 1,2,3,4,7,7-hexachloronorborna-2,5-diene affords a significant amount of 1,2,3,4,7,7-hexachloro-5-endo-ethoxynorborn-2-ene in addition to the major product 1,2,4,7,7-pentachloro-3-ethoxynorborna-2,5-diene reported earlier.
