Wr. Cullen et al., REACTION OF METHANOL WITH PERFLUOROTETRACYCLOBUTA-1,3,5,7-CYCLEOCTATETRAENE, Journal of fluorine chemistry, 76(2), 1996, pp. 121-124
erfluorotetracyclobuteno-1,3,5,7-cyclooctatetraene (PCOT) is a planar
and centrosymmetric molecule which possesses an extraordinary electron
affinity due to the planarity of the eight pi-electron system and the
cumulative electron-withdrawing effects of the 16 fluorine atoms. An
improved method for the synthesis of PCOT and the product resulting fr
om the spontaneous reaction of PCOT with excess alcohol is reported. C
rystal structures of the methyl (1) and ethyl (2) derivatives are desc
ribed.
