Behavior of Trifluoroacetohydrazonoyl Bromide in Basic Media

The bromide 1 was treated with sodium methoxide or phenoxide to give exclusively the corresponding substituted product.The predominant formation of the substituted products was also recognized with regard to various amines.However, the reaction with triet

PREPARATION OF TRIFLUOROACETONITRILE PHENYLAMINE AND ITS REACTIONS WITH SOME DIPOLAROPHILES

Trifluoroaceto-N-phenylhydrazonoyl halides, the precursors of trifluoroacetonitrile phenylamine, prepared by halogenation of trifluoroacetaldehyde phenylhydrazon, react with various olefins and acetylenes in the presence of triethylamine to give 3-trifluo
