Synthesis method of aryl trifluoroethylene compound
-
Paragraph 0037-0041; 0046-0081, (2021/04/10)
The invention belongs to the technical field of chemical synthesis, and particularly relates to a synthesis method of an aryl trifluoroethylene compound, and the main improvement lies in that trifluoroethylene and aryl sulfinate are used as raw materials and react under the catalytic action of a transition metal salt to obtain the aryl trifluoroethylene compound. The selected arylation reagent is novel, the reaction condition is simple and mild, the cost is low, the operation is easy and convenient, the cost is low, the universality is wide, the environmental pollution is small and the atom economy is high, and industrial large-scale production is expected to be achieved.

The construction of fluorocarbene ligands within the coordination sphere of transition metal complexes using sequential nucleophilic and electrophilic addition to a vinylidene complex is described. Reaction of [Ru(η5-C5H5)(dppe)(CCPhF)][N(SO2Ph)2] with [NMe4]F results in nucleophilic attack of fluoride at the metal-bound carbon of the vinylidene ligand to give alkenyl complex [Ru(η5-C5H5)(dppe)(-CFCFPh)]. Subsequent eletrophilic fluorination with N-fluorobenzenesulfonimide (NFSI) results in the formation of the fluorinated carbene complex [Ru(η5-C5H5)(dppe)(CF-CHFPh)][N(SO2Ph)2]. The fluorocarbene complexes undergo rearrangement to liberate free fluorinated alkenes, a process governed by the choice of solvent and anion, representing a new metal-mediated route to fluorinated alkenes from alkynes.
Method for synthesizing trifluoroarylethene compounds
-
Paragraph 0030-0075, (2018/05/16)
The invention relates to a method for synthesizing trifluoroarylethene compounds, belonging to the field of chemical synthesis. According to the method, trifluoroethylene is used as a starting raw material and reacts with easily available iodonium salts under proper conditions to produce the trifluoroarylethene compounds. Compared with traditional methods, the synthetic method provided by the invention has the characteristics of good universality, short reaction time, easy operation and the like; and since the synthetic method has the advantages of low cost, simple process, low pollution and the like, large-scale industrial production of the synthetic method can be realized.
