Hexafluoro-1,2-naphthalyne
Abstract
1,3,4,5,6,7,8-Heptafluoronaphthyl-lithium eliminates lithium fluoride to give only hexafluoro-1,2-naphthalyne, and not its 2,3-isomer, as shown by trapping with furan and by addition of undecomposed 1,3,4,5,6,7,8-heptafluoronaphthyl-lithium to give a characteristic mixture of tridecafluorobinaphthyls.
