Zusammenfassung:	A method of preparing a diorganodihalosilane, the method comprising the following separate and consecutive steps: (i) treating a preformed metal silicide with a mixture comprising hydrogen gas and a silicon tetrahalide at a temperature from 300 to 1400° C. to form a treated metal silicide, wherein the preformed metal silicide comprises a metal selected from at least one of Ni, Pd, or Pt; and (ii) reacting the treated metal silicide with an organohalide according to the formula RX at a temperature from 250 to 700° C. to form a diorganodihalosilane, wherein R is C1-C10 hydrocarbyl and X is halo.
