The stereoselective β-C(sp2)-H arylation of various acyclic enamides with arylsilanes via Rh(III)-catalyzed cross-coupling reaction was illustrated. The methodology was characterized by extraordinary efficacy and stereoselectivity, a wide scope of substrates, good functional group tolerance, and the adoption of environmentally friendly arylsilanes. The utility of this present method was evidenced by the gram-scale synthesis and further elaboration of the product. In addition, Rh(III)-catalyzed C-H activation is considered to be the critical step in the reaction mechanism.

Paragraph 0022; 0023, (2017/04/27)
The invention relates to a method for preparing naphthyl alkoxy silane monomers. The method comprises the following step: mixing alkoxy silane, sodium and 1-naphthalene halide to be reacted to obtain naphthyl alkoxy silane in an organic solvent, wherein the alkoxy silane is selected any one of tetramethoxysilane, methyltrimethoxysilane, tetraethoxysilane and methyl triethoxysilane. The method is easy to operate.
