<p>A method for preparing a reaction product includes separate and consecutive step (1) and step (2), where: step (1) is contacting, at a temperature from 200 °C to 1400 °C, an ingredient including a silane of formula HaRbSiX(4-a-b), where subscript a is 0 to 4, subscript b is 0 or 1, a quantity (a + b)≤4, each R is independently a monovalent organic group, and each X is independently a halogen atom, with the proviso that when the quantity (a + b) < 4, then the ingredient in step (1) further comprises H2; with a copper catalyst; thereby forming a reactant; and step (2) is contacting the reactant with an organohalide at a temperature from 100 °C to 600 °C; thereby forming the reaction product and a spent reactant. The reaction product is distinct from the silane used in step (1), and the reaction product includes a halosilane of formula R2S1X2, where each R is independently a monovalent organic group, and each X is independently a halogen atom.</p> |
