2-(2-(Dimethylamino)vinyll-6 pentafluorophenyl-4-phenylpyryliunt perchlorate has been synthesized and it was shown that it is readily converted into 2-fornrylntethylene-6-pentafluorophenyl-4-phenyl-2H-pyran on chromatography on alkaline Al2O3. The stereoisornerism of the synthesized compounds has been studied by PMR spectroscopy.
