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.

Herein, a copper-catalyzed C?F bond defluorosilylation reaction of tetrafluoroethylene and other polyfluoroalkenes is described. Mechanistic studies, based on a series of stoichiometric reactions with copper complexes, revealed that the key steps of this defluorosilylation reaction are 1) the 1,2-addition of a silylcopper intermediate to the polyfluoroalkene and 2) a subsequent selective β-fluorine elimination, which generates a Cu?F species. The β-fluorine elimination is facilitated by Lewis acidic F?Bpin, which is generated in situ during the defluorosilylation.
