Synthesis of 1-[4-(1,3-diaryl-4,5-dihydro-1H-pyrazol-5-yl)-2,3,5,6-tetrafluorophenyl]piperidin-4-ols and their acrylates

(4-Hydroxypiperidin-1-yl)tetra- and -octafluorochalcones reacted with phenylhydrazine in acetic acid to give mixtures of polyfluoro-1,3,5-triaryl-4,5-dihydro-1H-pyrazoles and their O-acetyl derivatives. Analogous reactions in ethanol afforded in satisfact

Formyl Derivatives of Amino-Substituted Polyfluorotriphenyl-4,5-dihydro-1H-pyrazoles: Synthesis and Use as Donor Blocks of Nonlinear Optical Chromophores

A series of new formyl derivatives of polyfluorinated triphenyl-4,5-dihydro-1H-pyrazoles containing various amine residues in the fluorinated benzene ring have been synthesized and used as donor building blocks in the synthesis of donor–acceptor dyes as potential chromophores for nonlinear electro-optics. Effects of substituents in the donor and acceptor moieties of the obtained chromophores on their spectral characteristics have been studied.

Reactions of polyfluorinated chalcones with hydrazine hydrate and phenylhydrazine

Polyfluorinated di- and triarylpyrazolines were synthesized by the reactions of polyfluorinated chalcones with hydrazine hydrate and phenylhydrazine, respectively. Reactions of benzyl-idenepolyfluoroacetophenones with phenylhydrazine resulted in the mixtures of isomeric 1,5-diphenyl-3- polyfluoroaryl-and 1,3-diphenyl-5-polyfluoroarylpyrazolines. Fluorescence properties of the synthesized triarylpyrazolines were studied.
