  • Method of preparing dialkyl-, diaryl-, and alkylaryl-dihalosilanes with high selectivity in a Grignard coupling reaction
    Patent number: 9828394
    Abstract: A method of making a diakyl-, diaryl-, or alkylaryl-dihalosilane in a Grignard coupling reaction with a high degree of selectivity is provided. More specifically, a Grignard reagent comprising an alkyl- or aryl-magnesium halide is allowed to react with an alkyl- or aryl-trihalosilane precursor or reagent to produce a product mixture of R2SiX2 and R3SiX, wherein each R is independently selected to be an alkyl or aryl group and X is a halogen group, such that the R2SiX2 product is formed with a high degree of selectivity. High selectivity is defined as the mass ratio of R2SiX2 product to the R3SiX product that is formed in the reaction being greater than 7:1.
