- Atom-economical synthesis of 3,3,3-trifluoropropanal dialkyl acetals through Pd/C catalyzed acetalization of 3,3,3-trifluoropropene
-
A facile and efficient procedure for one-step synthesis of 3,3,3-trifluoropropanal dialkyl acetals from readily available 3,3,3-trifluoropropene (TFP) has been developed. The catalyst can be recycled for 4 times without obvious deactivation. This process provides a novel and atom-economical synthetic strategy for the preparation of functional CF3-containing compounds.

- Alternative synthetic routes to hydrofluoroolefins
-
A series of hydrofluoroolefins with -CF=CH2, -CH=CHF and -CH=CF2 groups were designed and prepared via various synthetic routes, including HX or BrF elimination, Wittig-type olefination or fluorination using SF4.

- β-PERFLUOROALKYLVINYL ALKYL ETHERS
-
A convenient method was developed for the synthesis of β-perfluoroalkyl-substituted vinyl ethers by the reaction of vinyl alkyl ethers with perfluoroalkyl iodides in the presence of a palladium catalyst.Fluorine-containing aldehydes and their acetals, in which the perfluoroalkyl radical is separated from the formyl group by a methylene unit, were synthesized from the ethers.These aldehydes can be used for the synthesis of β-perfluoroalkyldicarbocyanines.

- Preparation of polyfluoroaldehydes and polyfluoroacetals
-
A group of polyfluoroaldehydes represented by 3,3,3-trifluoropropanal can be formed with very good selectivity by reacting polyfluoroalkenes represented by 3,3,3-trifluoropropene with water in the presence of a source of divalent palladium. A group of polyfluoroacetals represented by 1,1-dialkoxy-3,3,3-trifluoropropane can be formed with very good selectivity by reacting the same polyfluoroalkenes with an alcohol in the presence of a source of divalent palladium.
