Abstract

Abstract The synthesis of 2-chlorononafluorobiphenyl is described but it cannot be obtained by decomposing pentafluorophenyllithium in the presence of chloropentafluorobenzene. Tetrafluorobenzyne adds to styrene to give 1, 2, 3, 4-tetrafluorophenanthrene and 1, 2, 3, 4- tetrafluorodihydrophenanthrene. 2, 2′-Dilithiooctafluorobiphenyl readily loses one molecule of lithium fluoride at 0 to give 1-lithioheptafluorobiphenylene from which other ...
