In the past, the electrochemical properties of organosilicon compounds were investigated for both fundamental reasons and synthesis purposes. Little is, however, known about the electrochemical behaviour of hydrogen-bearing arylsilanes. Here, we throw light on the electrochemical properties of 11 arylsilanes compounds, 2 of them synthesized for the first time. The oxidation potentials are found to depend on both the nature and number of the aryl groups. Based on these findings it was possible to establish some variation trends that match the expected structure–property correlations. Furthermore, we present first insights into the electrochemical reaction kinetics behind and identify several soluble electrochemical oxidation products.

Paragraph 0041-0050, (2019/07/04)
The invention discloses a preparation method of phenyl chlorosilane. The preparation method comprises the following steps: (1) adding silicon powder, a copper catalyst and a sodium-containing compoundinto a reactor; (2) introducing a silicon-copper contact body modifier to pre-treat a silicon-copper contact body at a temperature of 300-500 DEG C; (3) mixing the pretreated silicon-copper contact body with a Cu-CuO-Cu2O-CuCl quaternary copper powder catalyst, and adding the mixture into the reactor; and (4) introducing chlorobenzene, controlling the reaction temperature to be 400-700 DEG C, andcarrying out a reaction to prepare phenyl chlorosilane monomers. According to the method, the use amount of the copper catalyst is low, the conversion rate of chlorobenzene is high, selectivity of phenyl chlorosilane is good, and the yield of diphenyl dichlorosilane with relatively high economic value is high in the product, so that economical efficiency of the phenyl chlorosilane prepared by thedirect method is improved.
