A METHOD OF PREPARING DIALKYL-DIARYL-, AND ALKYLARYL-DIHALOSILANES WITH HIGH SELECTIVITY IN A GRIGNARD COUPLING REACTION |
摘要 |
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 R2S1X2 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. |
