, p. 1891 - 1896 (2007/10/02)
5-Fluorocyclopentadiene 2 has been prepared by the reaction of cyclopentadienylthallium and the F(+) source, 1-chloromethyl-4-fluoro-1,4-diazoniabicyclooctane bis(tetrafluoroborate).In their reactions with compound 2, dienophiles form adducts having exclusively syn orientation.
