Claim Text:
1. A process comprising: reacting an oligomeric silane or a mixture comprising an organic silane in the presence of hydrogen halide over a catalyst, thereby obtaining a silicon compound of formula I: wherein each X is independently a halogen, n is 1 or 2, x is an integer between 0 to 6, y is an integer between 0 to 6, y+x=2n+2, the oligomeric silane or mixture comprising an organic silane comprises three directly covalently connected silicon atoms, and substituents on said organic silane comprising three directly covalently connected silicon atoms are each halogen, hydrogen, or oxygen; wherein the catalyst consists of an amino-functionalized compound or a monomeric or oligomeric aminosilane derived therefrom chemically bonded to a support material, a hydrocarbon-substituted amine, or a divinylbenzene-crosslinked polystyrene resin comprising tertiary amine groups, the amino-functionalized compound, if present, comprises alkyl-functionalized secondary, tertiary, or quaternary amino groups, or a combination thereof, the amino-functionalized compound, if present, is a compound of formula V or a hydrolysis product thereof, condensation product thereof, or both: z is an integer from 1 to 4, g is an integer from 1 to 10, d is an integer from 1 to 3, the hydrocarbon-substituted amine if present is of formula VI or VII: k=0, 1, or 2, each R is independently an aliphatic linear or branched or cycloaliphatic or aromatic hydrocarbon having 1 to 20 carbon atoms l=0, 1, 2, or 3, each R Z is an anion wherein the oligomeric silane or the mixture comprises a trisilicon compound, tetrasilicon compound, pentasilicon compound, hexasilicon compound, polysilicon compound, or any combination thereof.
