Kinetic Studies of the Continuous Wave Laser-Induced Cyclization of Hexafluoro-1,3-butadiene

Kinetics of the isomerisation of hexafluoro-1,3-butadiene have been studied in the past by standard pyrolysis and by shock tubes, with conflicting results.The present study indicates that the pyrolysis results are correct and also indicates that vibrational-translational energy in hexafluoro-1,3-butadiene occurs through a vibrational mode that is nearly harmonic.

A T-shaped Ni[κ2-(CF2)4-] NHC complex: Unusual Csp3-F and M-CF bond functionalization reactions

A T-shaped octafluoronickelacyclopentane-NHC complex is prepared and characterized. While the solid-state structure includes a weak isopropyl-CH3 agostic interaction, the reactivity of this complex with Lewis- and Bronsted acids is clearly enhanced by its low coordination number. Reaction with Me3SiOTf, for example, yielded a rare metal-heptafluorocyclobutyl complex whereas carboxylic acids gave substitution at the α-carbon and/or Ni-CF bond protonolysis to afford thermally robust 4H-octafluorobutyl Ni complexes.

MANUFACTURING METHOD OF PERFLUOROCYCLOALKENE COMPOUND

PROBLEM TO BE SOLVED: To obtain a perfluorocycloalkene compound high in conversion ratio of a reaction at high yield and high selectivity. SOLUTION: A perfluorocycloalkene compound represented by (1), where R1 to R4 are same or different, and represent a fluorine atom or a perfluoroalkadiene compound, is obtained by conducting a cyclization reaction of a perfluoroalkanediene compound represented by CR12=CR2-CR3=CR42, where R1 to R4 are same or different and represent a fluorine atom or a perfluoroalkyl group. The cyclization reaction can be conducted in presence of a catalyst, by a gas phase continuous flow type, or by the gas phase continuous flow type in presence of the catalyst.
