Method for preparing coupling arene from aryl halide by ionizing, discharging and coupling

The invention discloses a method for preparing coupling arene from aryl halide by ionizing, discharging and coupling. The method comprises the following steps: placing a magnetic stirrer into a three-necked flask and adding aryl halide occupying 1/2 flask, thereby finishing the assembling of an ionizing reaction device; placing the ionizing reaction device into an oil bath pan, introducing inert gas into a reaction system, removing air from the reaction system, starting stirring and heating in the oil bath pan to make aryl halide flow back, and meanwhile, introducing water into a ball-shaped condensation pipe for cooling; starting a high-voltage power generator, and introducing powerful arc generated into the three-necked flask through a metal electrode, thereby ionizing and decomposing aryl halide steam and generating a coupling arene compound; stopping ionizing and heating when solids are separated or the backflow of aryl halide is slowed in a round-bottom flask, and then ending the reaction; recrystallizing or performing reduced pressure distillation purification on the coupling arene product in the flask, thereby acquiring the coupling arene product. The method disclosed by the invention has the advantages of low cost, high efficiency, environmental protection, and the like.

Chlorinated and brominated aryltrisilanes ClnSi3Ar8-n and BrnSi3Ar8-n (Ar = phenyl, p-tolyl) as well as tetrasilanes (Ar = phenyl) have been synthesized. In a first step, Ph3SiSiPh2SiPh3, Ph3SiSiClPhSiPh3, p-Tol3SiSiPh2SiPh3, Ph3SiSip-Tol2SiPh3, Cl3SiSiCl2SiPh3 or H(SiPh2)4H have been prepared, and subsequently treated with trifluoromethanesulfonic acid (CF3SO3H), followed by a nucleophilic substitution of the triflate substituent (CF3O2SO) with X- (X = Cl, Br, H). The physical properties of the resulting compounds, which are valuable precursors for the synthesis of aryltrisilanes HnSi3Ar8-n and aryltetrasilanes HnSi4Ar10-n, have been described and their IR and 29Si NMR spectra have been reported.
