Synthesis and characterization of trichloroarylsilanes

The chemistry of primary alkyl and aryl functionalized silicon compounds of the general formula RSiHnX3-n, (R = alkyl or aryl, X = halide) is well established.1 Organotrichlorosilanes are widely used as starting materials in silicone industry and as coupling agents for the composites with inorganic materials in plastic. Over the last few decades, considerable effort has been made to develop a convenient route to organosilicon compounds such as Rochow direct process, the reaction of chlorosilanes with organometallic reagents, hydro- silylation, etc.2 The classical synthetic procedure can be separated in the formation of a carbanion at the aryl carbon, forming an organolithium or a Grignard reagent. Herein, trichloro(naphthalen-1-yl)silane was prepared by an one-pot reaction of naphthalen-1-ylmagnesium bromide and tetrachlorosilane in THF and was isolated as a white solid.3 We using aryl compound and tetrachlorosilane in THF solvent whose structures were determined on the basis of their mass spectrum, 1H and 13C NMR, X-ray, TGA and IR spectroscopic data
