Abstract
A general synthetic access to functional 2,3,5,6-tetrafluoro-p-phenylenebis(phosphines) is presented, which should open the way to linear P-based conjugated systems incorporating an electron-deficient aryl moiety. 1,4-Bis[bis(diethylamino)phosphino]-2,3,5,6-tetrafluorobenzene (1) and 1,4-bis(dichlorophosphino)-2,3,5,6-tetrafluorobenzene were synthesized in 60% and 85% yield, resp., and were characterized by spectroscopic methods and x-ray crystallog. Caution: The dilithio intermediate in the prepn. of 1 is highly reactive and prone to LiF elimination at temps. >-50° under the formation of very reactive aryne species. [on SciFinder(R)]
