<p>A method includes: (i) combining ingredients to form a reactant, (ii) contacting H2 with the reactant to form an activated reactant; and (iii) contacting an organohalide with the activated reactant to form a spent reactant and a reaction product including a halosilane. The ingredients used in step (i) are: (a) SiO2, (b) a reducing agent, and (c) a silicide precursor. The halosilane produced by the method has formula RnHmSiX(4-n), where subscript n is 0 to 3, subscript m is 0 to 2, a quantity (n + m)≤3, each R is independently a hydrocarbyl group, and each X is independently a halogen atom.</p> |
