β-Polyfluoroalkyl-α,β-enones formed in the E,Z form are converted by the action of atmospheric oxygen into a 93∶7 mixture of E,Z and Z,E isomers in the dark and 60∶40 mixture of these isomers in the light. The Z isomer of 1-phenyl-4,4, 4-trifl

Esters of fluorinated acylpyruvic acids were obtained for the first time. PMR and IR spectroscopy, dipole moment measurements, and quantum chemical calculations showed that these compounds exist as equilibrium mixtures of E and Z enolic isomers.

1. It has been found that β-ketoesters containing highly fluorinated substituents [CF3, or H(CF2)4] react with ammonia to give β-aminocrotonate esters, or under severe conditions, β-ketoamides. The latter react with a tenfold excess of ammonia to

1. Polyfluorinated β-ketoesters in the Vilsmeier-Haack reaction form α-formyl-β-chlorovinyl esters. An unsubstituted β-chlorovinyl ester is formed in the case of methyl 4,4-difluoro-3-hydroxybutenoate along with the α-formyl derivative. 2. The r

1. The bromination of fluoroalkyl-substituted β-ketoesters using bromine gives unstable α-bromo derivatives which undergo intermolecular rearrangement to yield the starting β-ketoesters and α,α-dibromo-β-ketoesters. 2. An IR spectroscopic and d

1. The magnitudes and directions of the dipole moments of fluoroalkyl groups X(CF2)n, where X=F or H, n=1, 2, and 4, have been determined. It has been revealed that there is an increase in the dipole moments of fluoroalkyl groups as the number of F a
