Treatment of pentafluoroacetophenone with fluorinated phenylhydrazine
in polyphosphoric acid (PPA) afforded new 2-pentafluorophenyl-5/6-fluo
roindoles. These 2-pentafluorophenyl-5/6-fluoroindoles on treatment wi
th various electrophiles yielded potential biologically active S-subst
ituted compounds. New compounds have been characterized by their analy
tical and spectral (IR, PMR, F-19 NMR and Mass) data.
