A method for preparing a reaction product comprising an aryl-functional silane comprising one or more of Ph 2 SiCl 2, PhHSiCl 2 and PhSiCl 3, where Ph represents phenyl, and the method comprises sequential steps and, where: step is contacting, under silicon deposition conditions at a first temperature, an ingredient comprising a halosilane of formula H a SiX (4-a), where each X is Cl-, and 0 ≤ a ≤ 1; and optionally H 2, with the proviso that when a = 0, then the hydrogen is present; and a metal combination comprising copper and palladium, and at least one other metal, where the at least one other metal is selected from the group consisting of, iron, and nickel; thereby forming a silicon alloy catalyst comprising silicon, copper, palladium and the at least one other metal; and step is contacting the silicon alloy catalyst and a reactant comprising an aryl halide of formula R 1 X, where R 1 is a phenyl group, under silicon etching conditions at a temperature lower than the first temperature of step; thereby forming the reaction product, where the reaction product comprises the aryl-functional silane and a spent catalyst; where the method may optionally further comprise step and step, where step is contacting, under the silicon deposition conditions, an additional ingredient comprising an additional halosilane of formula H a SiX (4-a) and optionally additional H 2; thereby re-forming the silicon alloy catalyst, and step is contacting the silicon alloy catalyst re-formed in step with an additional reactant comprising an additional aryl halide; thereby forming an additional amount of the reaction product, where the reaction product comprises the aryl-functional silane and the spent catalyst; and where the method, when further comprising steps and, optionally further comprises step, where step is repeating steps and at least one time; and where the method optionally further comprises step, where step is recovering the aryl-functional silane after step, and/or when present, step, and/or step. step is contacting, under silicon deposition conditions at a first temperature, an ingredient comprising a halosilane of formula H a SiX (4-a), where each X is Cl-, and 0 ≤ a ≤ 1; and optionally H 2, with the proviso that when a = 0, then the hydrogen is present; and a metal combination comprising copper and palladium, and at least one other metal, where the at least one other metal is selected from the group consisting of, iron, and nickel; thereby forming a silicon alloy catalyst comprising silicon, copper, palladium and the at least one other metal; and an ingredient comprising a halosilane of formula H a SiX (4-a), where each X is Cl-, and 0 ≤ a ≤ 1; and optionally H 2, with the proviso that when a = 0, then the hydrogen is present; and a metal combination comprising copper and palladium, and at least one other metal, where the at least one other metal is selected from the group consisting of, iron, and nickel; thereby forming a silicon alloy catalyst comprising silicon, copper, palladium and the at least one other metal; and step is contacting the silicon alloy catalyst and a reactant comprising an aryl halide of formula R 1 X, where R 1 is a phenyl group, under silicon etching conditions at a temperature lower than the first temperature of step; thereby forming the reaction product, where the reaction product comprises the aryl-functional silane and a spent catalyst; where the method may optionally further comprise step and step, where step is contacting, under the silicon deposition conditions, an additional ingredient comprising an additional halosilane of formula H a SiX (4-a) and optionally additional H 2; thereby re-forming the silicon alloy catalyst, and step is contacting the silicon alloy catalyst re-formed in step with an additional reactant comprising an additional aryl halide; thereby forming an additional amount of the reaction product, where the reaction product comprises the aryl-functional silane and the spent catalyst; and where the method, when further comprising steps and, optionally further comprises step, where step is repeating steps and at least one time; and where the method optionally further comprises step, where step is recovering the aryl-functional silane after step, and/or when present, step, and/or step.
