✦ Synopsis

Using 3,5-bis(trifluoromethyl)bromobenzene and methyltrimethoxysilane or tetraethoxysilane as raw materials, novel trifluoromethylphenyl silanes were synthesized via Grignard reaction and substitution reaction, and the molecular structure of silane products was characterized by NMR, FT-IR, MS techniques and elemental analysis. The reaction result showed that the reactivity of Grignard reagent was different in THF and diethyl ether when subjected to substitution reaction, which gave three products with different substitution degree. According to the current work, mono-, di-and tri-substituted product can be obtained selectively from the same reactants by controlling the reaction condition.
